LOW POWER STEREO AUDIO DAC FOR PORTABLE AUDIO/TELEPHONY  
1
FEATURES  
DESCRIPTION  
Stereo Audio DAC  
95-dBA Signal-to-Noise Ratio  
16/20/24/32-Bit Data  
The TLV320DAC32 is a low power stereo audio DAC  
with and integrated power amplifier designed to drive  
stereo headphones or speakers. This device also has  
a pair of analog inputs which allow routing of external  
signals to the output amplifiers. The playback path  
includes a mix/mux capability from the stereo DAC  
and analog inputs, through programmable volume  
controls, to the headphone outputs. Extensive  
register-based power control is included, enabling  
stereo 96-kHz playback as low as 20mW from a  
3.3-V analog supply, making it ideal for portable  
battery-powered audio and telephony applications.  
Supports Rates From 8 kHz to 96 kHz  
3D/Bass/Treble/EQ/De-emphasis Effects  
Two Audio Input Pins  
Allows Analog Bypass Path  
Four Audio Output Drivers  
Stereo 8-, 500-mW/Channel Speaker Drive  
Capability  
Stereo Fully Differential or Single-Ended  
Headphone Drivers  
The TLV320DAC32 contains four high-power output  
drivers. These drivers are capable of driving a variety  
of load configurations, including up to four channels  
of single-ended 16-headphones using ac-coupling  
capacitors, or stereo 16-headphones in a cap-less  
output configuration. In addition, pairs of drivers can  
be used to drive 8-speakers in a BTL configuration  
at 500 mW per channel.  
Low Power: 18-mW Stereo 48-kHz Playback  
With 3.3-V Analog Supply  
Programmable Input/Output Analog Gains  
Programmable Microphone Bias Level  
Headphone Jack Detection  
Programmable PLL for Flexible Clock  
Generation  
I2C Control Bus  
Audio Serial Data Bus Supports I2S,  
The stereo audio DAC supports sampling rates from  
8-kHz to 96-kHz and includes programmable digital  
filtering in the DAC path for 3D, bass, treble,  
midrange effects, speaker equalization, and  
de-emphasis for 32-kHz, 44.1-kHz, and 48-kHz rates.  
Left/Right-Justified, DSP, and TDM Modes  
Extensive Modular Power Control  
The serial control bus uses the I2C protocol, while the  
serial audio data bus is programmable for I2S,  
left/right-justified, DSP, or TDM modes. A highly  
programmable PLL is included for flexible clock  
generation and support for all standard audio rates  
from a wide range of available MCLKs, varying from  
512-kHz to 50-MHz, with special attention paid to the  
most popular cases of 12-MHz, 13-MHz, 16-MHz,  
19.2-MHz, and 19.68-MHz system clocks.  
Internal Selectable LDO Allows Operation  
From Single 3.3-V Supply  
Power Supplies:  
Analog: 2.7 V–3.6 V.  
Digital Core: 1.525 V–1.95 V  
Digital I/O: 1.1 V–3.6 V  
Package: 5 
נ
5 mm 32-QFN  
The TLV320DAC32 operates from analog supplies of  
2.7 V – 3.6 V, a digital core supply of 1.525 V – 1.95  
V, and a digital I/O supply of 1.1 V – 3.6 V. An  
internal LDO regulator allows the device to internally  
generate the lower voltage power supply needed for  
digital core logic, thereby allowing full operation from  
a single 3.3-V supply voltage.  
The TLV320DAC32 is a software-compatible subset  
of the existing TLV320AIC32 and TLV320AIC33  
audio codecs, allowing simple transition from a  
system with record and playback to a system with  
playback only.

OVERVIEW  
The TLV320DAC32 is a highly flexible, low power stereo audio DAC with extensive feature integration, intended  
for application in smartphones, PDAs, and portable computing, communication, and entertainment applications.  
Available in a 5x5mm 32-lead QFN, the product integrates a host of features to reduce cost, board space, and  
power consumption in space-constrained, battery powered portable applications.  
The TLV320DAC32 consists of the following blocks:  
Stereo audio multi-bit delta-sigma DAC (8 kHz – 96 kHz)  
Programmable digital audio effects processing (3-D, bass, treble, mid-range, EQ, de-emphasis)  
Two analog audio input pins  
Four high-power audio output drivers (headphone/speaker drive capability)  
Fully programmable PLL  
Programmable voltage level for microphone biasing  
Headphone/headset jack detection with interrupt  
Selectable internal LDO regulator for systems that only have +3.3V power available.  
The I2C interface supports both standard and fast communication modes.  
LDO OPERATION  
The TLV320DAC32 includes a LDO voltage regulator that can be used in systems where a 1.8V power supply is  
not available. In systems where the LDO is used, 3.3V power is applied to the device, and the internal LDO  
regulator generates the 1.8V needed to operate the internal digital core. The LDO functionality is controlled by  
the state of the LDO_SELECT pin (pin 5 in QFN package). To enable the LDO function, apply IOVDD to the  
LDO_SELECT pin. To disable the LDO function, connect the LDO_SELECT pin to ground. The correct operation  
of the device requires that the LDO_SELECT pin must be connected to either IOVDD or ground. When the LDO  
is bypassed, the DVDD pin must be connected to a 1.8V power supply.  
A small value ceramic capacitor should be connected between the DVDD pin and digital ground, even when the  
internal LDO is used. This capacitor provides power supply decoupling for either power supply condition. See  
Figure 21 and Figure 22 for proper connection and use of the internal LDO.

HARDWARE RESET  
The TLV320DAC32 requires a hardware reset after power-up for proper operation. After all power supplies are at  
their specified values, the RESET pin must be driven low for at least 10 ns. If this reset sequence is not  
performed, the 'DAC32 may not respond properly to register reads/writes.  
FLEXIBLE POWER DOWN  
The TLV320DAC32 allows power down for many individual circuit blocks. This flexibility allows the user to be  
able to optimize functionality while minimizing power consumption for each application. The power consumption  
for the device by function can be seen in Table 1.

DIGITAL CONTROL SERIAL INTERFACE  
The register map of the TLV320DAC32 actually consists of two pages of registers, with each page containing  
128 registers. The register at address zero on each page is used as a page control register, and writing to this  
register determines the active page for the device. All subsequent read/write operations will access the page that  
is active at the time, unless a register write is performed to change the active page. Only two pages of registers  
are implemented in this product, with the active page defaulting to page 0 upon device reset. The Page 0 is  
dedicated to DAC and device functionality setup, while Page 1 is used to setup the Digital Audio Effects  
Processor, and for use in applying digital de-emphasis to the digital audio playback stream.  
For example, at device reset, the active page defaults to page 0, and thus all register read/write operations for  
addresses 1 to 127 will access registers in page 0. If registers on page 1 must be accessed, the user must write  
the 8-bit sequence “0x01” to register 0, the page control register, to change the active page from page 0 to page  
1. After this write, it is recommended the user also read back the page control register, to safely ensure the

change in page control has occurred properly. Future read/write operations to addresses 1 to 127 will now  
access registers in page 1. When page 0 registers must be accessed again, the user writes the 8-bit sequence  
“0x00” to register 0, the page control register, to change the active page back to page 0. After a recommended  
read of the page control register, all further read/write operations to addresses 1 to 127 will now access page 0  
registers again.  
It is considered to be a best practice, that when writing to PAGE 1, all five of the digital filter’s coefficients of the  
Bi-Quad structure be updated to the new values before resuming digital audio playback.  
I2C CONTROL MODE  
The TLV320DAC32 supports the I2C control protocol using 7-bit addressing and is capable of both standard and  
fast modes. For I2C fast mode, note that the minimum timing for each of tHD-STA, tSU-STA, and tSU-STO is 0.9 µs, as  
seen in Figure 23. The TLV320DAC32 will respond to the I2C address of 0011000. I2C is a two-wire open-drain  
interface supporting multiple devices and masters on a single bus. Devices on the I2C bus only drive the bus  
lines LOW by connecting them to ground; they never drive the bus lines HIGH. Instead, the bus wires are pulled  
HIGH by pull-up resistors, so the bus wires are HIGH when no device is driving them LOW. This way, two  
devices cannot conflict; if two devices drive the bus simultaneously, there is no driver contention.

Figure 23. I2C Interface Timing  
Communication on the I2C bus always takes place between two devices, one acting as the master and the other  
acting as the slave. Both masters and slaves can read and write, but slaves can only do so under the direction of  
the master. Some I2C devices can act as masters or slaves, but the TLV320DAC32 can only act as a slave  
device.  
An I2C bus consists of two lines, SDA and SCL. SDA carries data; SCL provides the clock. All data is transmitted  
across the I2C bus in groups of eight bits. To send a bit on the I2C bus, the SDA line is driven to the appropriate  
level while SCL is LOW (a LOW on SDA indicates the bit is zero; a HIGH indicates the bit is one). Once the SDA  
line has settled, the SCL line is brought HIGH, then LOW. This pulse on SCL clocks the SDA bit into the  
receiver’s shift register.  
The I2C bus is bidirectional: the SDA line is used both for transmitting and receiving data. When a master reads  
from a slave, the slave drives the data line; when a master sends info to a slave, the master drives the data line.  
The master always drives the clock line. The TLV320DAC32 never drives SCL, because it cannot act as a  
master. On the TLV320DAC32, SCL is an input only.  
Most of the time the bus is idle, no communication is taking place, and both lines are HIGH. When  
communication is taking place, the bus is active. Only master devices can start a communication. They do this by  
causing a START condition on the bus. Normally, the data line is only allowed to change state while the clock  
line is LOW. If the data line changes state while the clock line is HIGH, it is either a START condition or its  
counterpart, a STOP condition. A START condition is when the clock line is HIGH and the data line goes from  
HIGH to LOW. A STOP condition is when the clock line is HIGH and the data line goes from LOW to HIGH.

After the master issues a START condition, it sends a byte that indicates which slave device it wants to  
communicate with. This byte is called the address byte. Each device on an I2C bus has a unique 7-bit address to  
which it responds. (Slaves can also have 10-bit addresses; see the I2C specification for details.) The master  
sends an address in the address byte, together with a bit that indicates whether it wishes to read from or write to  
the slave device.  
Every byte transmitted on the I2C bus, whether it is address or data, is acknowledged with an acknowledge bit.  
When a master has finished sending a byte (eight data bits) to a slave, it stops driving SDA and waits for the  
slave to acknowledge the byte. The slave acknowledges the byte by pulling SDA LOW. The master then sends a  
clock pulse to clock the acknowledge bit. Similarly, when a master has finished reading a byte, it pulls SDA LOW  
to acknowledge this to the slave. It then sends a clock pulse to clock the bit. (Remember that the master always  
drives the clock line.)  
A not-acknowledge is performed by simply leaving SDA HIGH during an acknowledge cycle. If a device is not  
present on the bus, and the master attempts to address it, it will receive a notacknowledge because no device  
is present at that address to pull the line LOW.  
When a master has finished communicating with a slave, it may issue a STOP condition. When a STOP  
condition is issued, the bus becomes idle again. A master may also issue another START condition. When a  
START condition is issued while the bus is active, it is called a repeated START condition.  
The TLV320DAC32 also responds to and acknowledges a General Call, which consists of the master issuing a  
command with a slave address byte of 00H.

In the case of an I2C register write, if the master does not issue a STOP condition, then the device enters  
auto-increment mode. So in the next eight clocks, the data on SDA will be treated as data for the next  
incremental register.  
Similarly, in the case of an I2C register read, after the device has sent out the 8-bit data from the addressed  
register, if the master issues a ACKNOWLEDGE, the slave will take over control of SDA bus and transmit for the  
next 8 clocks the data of the next incremental register.

DIGITAL AUDIO DATA SERIAL INTERFACE  
Audio data is transferred between the host processor and the TLV320DAC32 via the digital audio data serial  
interface, or “audio bus”. The audio bus of the TLV320DAC32 can be configured for left or right justified, I2S,  
DSP, or TDM modes of operation, where communication with standard telephony PCM interfaces is supported  
within the TDM mode. These modes are all MSB-first, with data width programmable as 16, 20, 24, or 32 bits. In  
addition, the word clock (WCLK) and bit clock (BCLK) can be independently configured in either master or slave  
mode, for flexible connectivity to a wide variety of processors.  
The word clock (WCLK) is used to define the beginning of a frame, and may be programmed as either a pulse or  
a square-wave signal. The frequency of this clock corresponds to the maximum DAC sampling frequency  
selected.  
The bit clock (BCLK) is used to clock in the digital audio data across the serial bus. When in master mode, this  
signal can be programmed in two further modes: continuous transfer mode, and 256-clock mode. In continuous  
transfer mode, only the minimal number of bit clocks needed to transfer the audio data are generated, so in  
general the number of bit clocks per frame will be two times the data width. For example, if data width is chosen  
as 16-bits, then 32 bit clocks will be generated per frame. If the bit clock signal in master mode will be used by a  
PLL in another device, it is recommended that the 16-bit or 32-bit data width selections be used. These cases  
result in a low jitter bit clock signal being generated, having frequencies of 32*Fs or 64*Fs. In the cases of 20-bit  
and 24-bit data width in master mode, the bit clocks generated in each frame will not all be of equal period, due  
to the device not having a clean 40*Fs or 48*Fs clock signal readily available. The average frequency of the bit  
clock signal is still accurate in these cases (being 40*Fs or 48*Fs), but the resulting clock signal has higher jitter  
than in the 16-bit and 32-bit cases and may reduce the overall DAC performance.  
In 256-clock mode, a constant 256 bit clocks per frame are generated, independent of the data width chosen. By  
using this capability with the ability to program at what bit clock in a frame the audio data will begin, time-division  
multiplexing (TDM) can be accomplished, resulting in multiple DACS able to use a single audio serial data bus.  
When the audio serial data bus is powered down while configured in master mode, the pins associated with the  
interface will be put into a tri-state output condition.  
RIGHT JUSTIFIED MODE  
In right-justified mode, the LSB of the left channel is valid on the rising edge of the bit clock preceding the falling  
edge of word clock. Similarly, the LSB of the right channel is valid on the rising edge of the bit clock preceding  
the rising edge of the word clock.

TDM DATA TRANSFER  
Time-division multiplexed data transfer can be realized in any of the above transfer modes if the 256-clock bit  
clock mode is selected, although it is recommended to be used in either left-justified mode or DSP mode. By  
changing the programmable offset, the bit clock in each frame where the data begins can be changed. For  
incoming data, the dac simply ignores data on the bus except where it is expected based on the programmed  
offset.  
Note that the location of the data when an offset is programmed is different, depending on what transfer mode is  
selected. In DSP mode, both left and right channels of data are transferred immediately adjacent to each other in  
the frame. This differs from left-justified mode, where the left and right channel data will always be a half-frame  
apart in each frame. In this case, as the offset is programmed from zero to some higher value, both the left and  
right channel data move across the frame, but still stay a full half-frame apart from each other. This is depicted in  
Figure 30 below for the two cases.

AUDIO DATA CONVERTERS  
The TLV320DAC32 supports the following standard audio sampling rates: 8-kHz, 11.025-kHz, 12-kHz, 16-kHz,  
22.05-kHz, 24-kHz, 32-kHz, 44.1-kHz, 48-kHz, 88.2-kHz, and 96-kHz.  
The data converter is based on the concept of an Fsref rate that is used internal to the part, and it is related to  
the actual sampling rates of the dac through a series of ratios. For typical sampling rates, Fsref will be either  
44.1-kHz or 48-kHz, although it can realistically be set over a wider range of rates up to 96-kHz, with additional  
restrictions applying if the PLL is used. This concept is used to set the sampling rates of the DAC, and also to  
enable high quality playback of low sampling rate data, without high frequency audible noise being generated.  
The sampling rate of the DAC can be set to Fsref/NDAC or 2*Fsref/NDAC, with NDAC being 1, 1.5, 2, 2.5, 3,  
3.5, 4, 4.5, 5, 5.5, or 6.  
AUDIO CLOCK GENERATION  
The audio dac in the TLV320DAC32 needs an internal audio master clock at a frequency of 256*Fsref, which can  
be obtained in a variety of manners from an external clock signal applied to the device.  
A more detailed diagram of the audio clock section of the TLV320DAC32 is shown in Figure 31.

Figure 31. Audio Clock Generation Processing  
The TLV320DAC32 can accept an MCLK input from 2-MHz to 50-MHz, which can then be passed through either  
a programmable divider or a PLL, to get the proper internal audio master clock needed by the part. Alternatively,  
the BCLK input can also be used to generate the internal audio master clock.  
A primary concern is proper operation of the dac at various sample rates with the limited MCLK frequencies  
available in the application system. This device includes a highly programmable PLL to accommodate such  
situations easily. The integrated PLL can generate audio clocks from a wide variety of possible MCLK inputs,  
with particular focus paid to the standard MCLK rates already widely used.  
When the PLL is disabled,

NOTE – when NDAC = 1.5, 2.5, 3.5, 4.5, or 5.5, odd values of Q are not allowed. In this mode, MCLK can be as

STEREO AUDIO DAC  
The TLV320DAC32 includes a stereo audio DAC supporting sampling rates from 8-kHz to 96-kHz. Each channel  
of the stereo audio DAC consists of a digital audio processing block, a digital interpolation filter, multi-bit digital  
delta-sigma modulator, and an analog reconstruction filter. The DAC is designed to provide enhanced  
performance at low sampling rates through increased oversampling and image filtering, thereby keeping  
quantization noise generated within the delta-sigma modulator and signal images strongly suppressed within the  
audio band to beyond 20-kHz. This is realized by keeping the upsampled rate constant at 128 x Fsref and  
changing the oversampling ratio as the input sample rate is changed. For an Fsref of 48-kHz, the digital  
delta-sigma modulator always operates at a rate of 6.144-MHz. This ensures that quantization noise generated  
within the delta-sigma modulator stays low within the frequency band below 20-kHz at all sample rates. Similarly,  
for an Fsref rate of 44.1-kHz, the digital delta-sigma modulator always operates at a rate of 5.6448-MHz.  
The following restrictions apply in the case when the PLL is powered down and double-rate audio mode is  
enabled in the DAC.  
Allowed Q values = 4, 8, 9, 12, 16  
Q values where equivalent Fsref can be achieved by turning on PLL  
Q = 5, 6, 7 (set P = 5 / 6 / 7 and K = 16.0 and PLL enabled)  
Q = 10, 14 (set P = 5, 7 and K = 8.0 and PLL enabled)  
DIGITAL AUDIO PROCESSING  
The DAC channel consists of optional filters for de-emphasis and bass, treble, midrange level adjustment,  
speaker equalization, and 3-D effects processing. The de-emphasis function is implemented by a programmable  
digital filter block with fully programmable coefficients (see Page-1/Reg-21-26 for left channel, Page-1/Reg-47-52  
for right channel). If de-emphasis is not required in a particular application, this programmable filter block can be  
used for some other purpose. The de-emphasis filter transfer function is given by:  
*1  
N0 ) N1   z  
H(z) +  
*1  
32768 * D1   z  
(1)  
where the N0, N1, and D1 coefficients are fully programmable individually for each channel. The coefficients that  
should be loaded to implement standard de-emphasis filters are given in Table 1.

In addition to the de-emphasis filter block, the DAC digital effects processing includes a fourth order digital IIR  
filter with programmable coefficients (one set per channel). This filter is implemented as cascade of two biquad  
sections with frequency response given by:  
N0 ) 2   N1   z*1 ) N2   z*2

The N and D coefficients are fully programmable, and the entire filter can be enabled or bypassed. The structure  
of the filtering when configured for independent channel processing is shown below in Figure 32, with LB1  
corresponding to the first left-channel biquad filter using coefficients N0, N1, N2, D1, and D2. LB2 similarly  
corresponds to the second left-channel biquad filter using coefficients N3, N4, N5, D4, and D5. The RB1 and  
RB2 filters refer to the first and second right-channel biquad filters, respectively.

The coefficients for this filter implement a variety of sound effects, with bass-boost or treble boost being the most  
commonly used in portable audio applications. The default N and D coefficients in the part are given in Table 2  
and implement a shelving filter with 0-dB gain from DC to approximately 150-Hz, at which point it rolls off to a  
3-dB attenuation for higher frequency signals, thus giving a 3-dB boost to signals below 150-Hz. The N and D  
coefficients are represented by 16-bit two's complement numbers with values ranging from -32768 to +32767.

The digital processing also includes capability to implement 3-D processing algorithms by providing means to  
process the mono mix of the stereo input, and then combine this with the individual channel signals for stereo  
output playback. The architecture of this processing mode, and the programmable filters available for use in the  
system, is shown in Figure 33. Note that the programmable attenuation block provides a method of adjusting the  
level of 3-D effect introduced into the final stereo output. This combined with the fully programmable biquad filters  
in the system enables the user to fully optimize the audio effects for a particular system and provide extensive  
differentiation from other systems using the same device.

Figure 33. Architecture of the Digital Audio Processing When 3-D Effects are Enabled  
It is recommended that the digital effects filters should be disabled while the filter coefficients are being modified.  
Since updating all 5 digital coefficients using the I2C control port can take more than 1 LRCLK cycle, it is  
therefore possible that a filter using partially updated coefficients may actually implement an unstable filter and  
lead to an oscillation or objectionable audio output. By first disabling the filters, then changing the all of the  
coefficients as needed, and then re-enabling the filters, these types of effects can be entirely avoided.  
DIGITAL INTERPOLATION FILTER  
The digital interpolation filter upsamples the output of the digital audio processing block by the required  
oversampling ratio before data is provided to the digital delta-sigma modulator and analog reconstruction filter  
stages. The filter provides a linear phase output with a group delay of 21/Fs. In addition, programmable digital  
interpolation filtering is included to provide enhanced image filtering and reduce signal images caused by the  
upsampling process that are below 20-kHz. For example, upsampling an 8-kHz signal produces signal images at  
multiples of 8-kHz (i.e., 8-kHz, 16-kHz, 24-kHz, etc). The images at 8-kHz and 16-kHz are below 20-kHz and still  
audible to the listener; therefore, they must be filtered heavily to maintain a good quality output. The interpolation  
filter in this device is designed to maintain at least 65-dB rejection of images that land below 7.455 Fs. In order to  
utilize the programmable interpolation capability, the Fsref should be programmed to a higher rate (restricted to  
be in the range of 39-kHz to 53-kHz when the PLL is in use), and the actual Fs is set using the NDAC divider.  
For example, if Fs = 8-kHz is required, then Fsref can be set to 48-kHz, and the DAC Fs set to Fsref/6. This  
ensures that all images of the 8-kHz data are sufficiently attenuated well beyond a 20-kHz audible frequency  
range.  
DELTA-SIGMA AUDIO DAC  
The stereo audio DAC incorporates a third order multi-bit delta-sigma modulator followed by an analog  
reconstruction filter. The DAC provides high-resolution, low-noise performance, using oversampling and noise  
shaping techniques. The analog reconstruction filter design consists of a 6 tap analog FIR filter followed by a  
continuous time RC filter. The analog FIR operates at a rate of 128 x Fsref (6.144 MHz when Fsref = 48-kHz,  
5.6448-MHz when Fsref = 44.1-kHz). Note that the DAC analog performance may be degraded by excessive  
clock jitter on the MCLK input. Therefore, care must be taken in the system design to keep jitter on this clock to a  
minimum.

AUDIO DAC DIGITAL VOLUME CONTROL  
The audio DAC includes a digital volume control block which implements a programmable digital gain. The  
volume level can be varied from 0-dB to –63.5-dB in 0.5-dB steps, in addition to a mute bit, independently for  
each channel. The volume level of both channels can also be changed simultaneously by the master volume  
control. Gain changes are implemented with a soft-stepping algorithm, which only changes the actual volume by  
a maximum of one step per input sample, either up or down, until the desired volume level is reached. The rate  
of soft-stepping can be further slowed to one step per two input samples through a register bit.  
Because of soft-stepping, the host does not know the exact time that the DAC has been actually muted. This  
may be important if the host wishes to mute the DAC before making a significant change, such as changing  
sample rates. In order to help with this situation, the device provides a flag back to the host via a read-only  
register bit that alerts the host when the part has completed the soft-stepping and the actual volume has reached  
the desired volume level. These flags can be found at register locations: Page0/Reg-51/D1, Page0/Reg-58/D1,  
Page0/Reg-65/D1, Page0/Reg-72/D1. The soft-stepping feature can be disabled through register programming. If  
soft-stepping is enabled, the MCLK signal should be kept applied to the device until the DAC power-down flag is  
set. When this flag is set, the internal soft-stepping process and power down sequence is complete, and the  
MCLK can then be stopped if desired.  
The TLV320DAC32 also includes functionality to detect when the user switches on or off the de-emphasis or  
digital audio processing functions. It is recommended to first (1) soft-mute the DAC volume control, (2) change  
the operation of the digital effects processing by downloading the new filter coefficients to the appropriate  
registers, and then (3) soft-unmute the device. This avoids any possible pop/clicks in the audio output due to  
instantaneous changes in the filtering. A similar algorithm should be used when first powering up or down the  
DAC. The system should begin operation at power up with the volume control muted, then soft-steps the volume  
up to the desired volume level. At power down, the logic first soft-steps the volume down to the mute level, and  
then powers down the circuitry.  
AUDIO DAC COMMON-MODE ADJUSTMENT  
The output common-mode voltage and output range of the audio DAC are determined by an internal bandgap  
reference, in contrast to other DACS that may use a resistor-divider version of the supply. This voltage reference  
scheme is used to reduce the coupling of power supply noise (such as 217-Hz noise in a GSM cellphone) into  
the audio signal path.  
However, due to the possible wide variation in analog supply range (2.7V – 3.6V), an output common-mode  
voltage setting of 1.35V, which would be used for a 2.7V supply case, will be overly conservative if the supply is  
actually much larger, such as 3.3V or 3.6V. In order to optimize device operation, the TLV320DAC32 includes a  
programmable output common-mode level, which can be set by register programming to a level most appropriate  
to the actual supply range used by a particular application. The output common-mode level can be varied among  
four different values, ranging from 1.35V (most appropriate for low supply ranges, near 2.7V) to 1.8V (most  
appropriate for high supply ranges, near 3.6V). Note that there is also some limitation on the range of DVDD  
voltage as well in determining which setting is most appropriate .

AUDIO DAC POWER CONTROL  
The stereo DAC can be fully powered up or down, and in addition, the analog circuitry in each individual DAC  
channel can be powered up or down independently. This provides power savings when only a mono playback  
stream is needed.

AUDIO ANALOG INPUTS  
The TLV320DAC32 includes two single-ended audio inputs that are sent to an output mixer with volume control  
capability. By configuring the mixer to accept multiple inputs, an analog mixing function occurs. Mixing of multiple  
mixer inputs can easily lead to outputs that exceed the range of the internal opamps, thereby resulting in  
saturation and clipping of the mixed output signal. Note that whenever mixing is being implemented, the user  
should take adequate precautions to avoid such a saturation case from occurring. In general, the analog mixed  
signal should not exceed 2Vp-p (single-ended).  
In most mixing applications, there is also a general need to adjust the levels of the individual signals being  
mixed. For example, if a soft signal and a large signal are to be mixed and played together, the soft signal  
generally should be amplified to a level comparable to the large signal before mixing. In order to accommodate  
this need, the TLV320DAC32 includes input volume control on each of the individual inputs before they are  
mixed, with gain programmable from 0dB to -78dB in 0.5dB steps. Soft-stepping of the input level control settings  
is implemented in this device, with the speed and functionality following the settings used by the DAC.  
ANALOG INPUT BYPASS PATH FUNCTIONALITY  
The TLV320DAC32 includes the additional ability to route two analog input signals around the DAC and then  
connect to the output drivers. This capability is useful in a cellphone, for example, when a separate FM radio  
device provides a stereo analog output signal that needs to be routed to headphones. The TLV320DAC32  
supports this in a low power mode by providing a direct analog path through the device to the output drivers,  
while the DACS can be completely powered down to save power. When programmed correctly, the device can  
connect the analog input signals LINEL and LINER through the volume control which is connected to the output  
stage.  
MICBIAS GENERATION  
The TLV320DAC32 includes a programmable microphone bias output voltage (MICBIAS), capable of providing  
output voltages of 2.0V or 2.5V (both derived from the on-chip bandgap voltage) with 4mA output current drive.  
In addition, the MICBIAS may be programmed to be switched to AVDD_DAC directly through an on-chip switch,  
or it can be powered down completely when not needed, for power savings. This function is controlled by register  
programming in Page-0/Reg-25.  
ANALOG HIGH POWER OUTPUT DRIVERS  
The TLV320DAC32 includes four high power output drivers with extensive flexibility in their usage. These output  
drivers are individually capable of driving 40mW each into a 16-load in single-ended configuration, and they  
can be used in pairs to drive up to 325mW into an 8-load connected in bridge-terminated load (BTL)  
configuration between two driver outputs.  
The high power output drivers can be configured in a variety of ways, including:  
driving up to two fully differential output signals  
driving up to four single-ended output signals  
driving two single-ended output signals, with one or two of the remaining drivers driving a fixed VCM level, for  
a pseudo-differential stereo output  
driving one or two 8-speakers connected BTL between pairs of driver output pins  
driving stereo headphones in single-ended configuration with two drivers, while the remaining two drivers are  
connected in BTL configuration to an 8-speaker  
The output stage architecture with the volume control and mixing blocks leading to the high power output drivers  
is shown in Figure 34. Note that each of these drivers have a output level control which allows gain adjustments  
up to +9dB on the output signal. Note that this output level adjustment is not intended to be used as a standard  
volume control, but instead is included for additional full-scale output signal level control.  
The output drivers, HPROUT and HPLOUT, include a direct connection path (L/R DAC_Direct) between the  
stereo DAC outputs and the output drivers. This pathway allows bypassing of the analog volume controls and the  
mixing networks. This functionality provides the highest quality DAC playback performance while reducing power  
dissipation, but this mode can only be utilized if the DAC output does not need to be mixed with the external  
analog input signals.

Figure 34. Architecture of the output stage leading to the high power output drivers  
The high power output drivers include additional circuitry to avoid artifacts on the audio output during power-on  
and power-off transient conditions. The user should first program the type of output configuration being used in  
Page-0/Reg-14, to allow the device to select the optimal power-up scheme to avoid output artifacts. The  
power-up delay time for the high power output drivers is also programmable over a wide range of time delays,  
from instantaneous up to 4-sec, using Page-0/Reg-42.  
When these output drivers are powered down, they can be placed into a variety of output conditions based on  
register programming. If lowest power operation is desired, then the outputs can be placed into a tri-state  
condition, and all power to the output stage is removed. However, this generally results in the output nodes  
drifting to rest near the upper or lower analog supply voltage, due to small leakage currents at the pins. This then  
results in a longer delay requirement to avoid output artifacts (pops and clicks) during driver power-on. In order to  
reduce this required power-on delay, the TLV320DAC32 includes an option for the output pins of the drivers to  
be weakly driven to the VCM level they would normally rest at when powered with no signal applied. This output  
VCM level is determined by an internal bandgap voltage reference, and thus results in extra power dissipation  
when the drivers are in power down. However, this option provides the fastest method for transitioning the drivers  
from power down to full power operation without any output artifact introduced.

The device includes a further option that falls between the other two – while it requires less power drawn while  
the output drivers are in power down, it also takes a slightly longer delay to power-up without artifact than if the  
bandgap reference is kept powered up. In this alternate mode, the powered-down output driver pin is weakly  
driven to a voltage of approximately half the DRVDD1/2 supply level using an internal voltage divider. This  
voltage will not match the actual VCM of a fully powered driver, but due to the output voltage being close to its  
final value, a much shorter power-up delay time setting can be used and still avoid any audible output artifacts.  
These output voltage options are controlled in Page-0/Reg-42.  
The high power output drivers can also be programmed at power up with the output level control in a highly  
attenuated state, and when UN-Muted, the output driver will automatically slowly increase the gain to reach the  
desired output level setting that was programmed prior to the Un-Mute setting. This capability is disabled by  
default setting but can be enabled in Page-0/Reg-40.  
SHORT CIRCUIT OUTPUT PROTECTION  
The TLV320DAC32 includes programmable short-circuit protection for the high power output drivers, for  
maximum flexibility in a given application. By default, if these output drivers are shorted, they will automatically  
limit the maximum amount of current that can be sourced to or sunk from a load, thereby protecting the device  
from an over-current condition. In this mode, the user can read Page-0/Reg-95 to determine whether the part is  
in short-circuit protection or not, and then decide whether to program the device to power down the output  
drivers. However, the device includes further capability to automatically power down an output driver whenever it  
does enter into short-circuit protection, without requiring intervention from the user. In this case, the output driver  
will stay in a power down condition until the user specifically programs it to power down and then power back up  
again, to clear the short-circuit flag.  
JACK / HEADSET DETECTION  
The TLV320DAC32 includes extensive capability to monitor a headphone, microphone, or headset jack,  
determine if a plug has been inserted into the jack, and then determine what type of headset/headphone is wired  
to the plug. Figure 35 shows one configuration of the device that enables detection and determination of headset  
type when a pseudo-differential (capless) stereo headphone output configuration is used. The registers used for  
this function are Page-0/Reg 14, 37, 38, and 13. The type of headset detected can be read back from  
Page-0/Reg-13. Note that for best results, it is recommended to select a MICBIAS value as high as possible, and  
to program the output driver common-mode level at a 1.35V or 1.5V level.

An output configuration for the case of the outputs driving fully differential stereo headphones is shown in  
Figure 37. In this mode there is a requirement on the jack side that either HPLCOM or HPLOUT get shorted to  
ground if the plug is removed, which can be implemented using a spring terminal in a jack. For this mode to  
function properly, short-circuit detection should be enabled and configured to power-down the drivers if a  
short-circuit is detected. The registers that control this functionality are in Page-0/Reg-38/Bit-D2-D1.

Audio Serial Data Word Offset Control  
This register determines where valid data is placed or expected in each frame, by controlling  
the offset from beginning of the frame where valid data begins. The offset is measured from  
the rising edge of word clock when in DSP mode.  
00000000: Data offset = 0 bit clocks  
00000001: Data offset = 1 bit clock  
00000010: Data offset = 2 bit clocks  
Note: In continuous transfer mode the maximum offset is 17 for I2S/LJF/RJF modes and 16  
for DSP mode. In 256-clock mode, the maximum offset is 242 for I2S/LJF/RJF and 241 for  
DSP modes.  
11111110: Data offset = 254 bit clocks  
11111111: Data offset = 255 bit clocks

Output Stage Volume Controls  
A basic analog volume control with range from 0 dB to -78 dB and mute is replicated multiple times in the output  
stage network, connected to each of the analog signals that route to the output stage. In addition, to enable  
completely independent mixing operations to be performed for each output driver, each analog signal coming into  
the output stage may have up to four separate volume controls. These volume controls all have approximately  
0.5-dB step programmability over most of the gain range, with steps increasing slightly at the lowest attenuations.  
Table 5 lists the detailed gain versus programmed setting for this basic volume control.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".  
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  
(6)  
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two  
lines if the finish value exceeds the maximum column width.
