DESCRIPTION  
The TPA6130A2 is a stereo DirectPath™ headphone amplifier with I2C digital volume control. The TPA6130A2  
has minimal quiescent current consumption, with a typical IDD of 4 mA, making it optimal for portable  
applications. The I2C control allows maximum flexibility with a 64 step audio taper volume control, channel  
independent enables and mutes, and the ability to configure the outputs into stereo, dual mono, or a single  
receiver speaker BTL amplifier that drives 300 mW of power into 16 loads.  
The TPA6130A2 is a high fidelity amplifier with an SNR of 98 dB. A PSRR greater than 100 dB enables  
direct-to-battery connections without compromising the listening experience. The output noise of 9 µVrms  
(typical A-weighted) provides a minimal noise background during periods of silence. Configurable differential  
inputs and high CMRR allow for maximum noise rejection in the noisy environment of a mobile device.  
TPA6130A2 packaging includes a 2 by 2 mm chip-scale package, and a 4 by 4 mm QFN package.

Headphone channels are independently enabled and muted. The I2C interface controls channel gain, device  
modes, and charge pump activation. The charge pump generates a negative supply voltage for the output  
amplifiers. This allows a 0 V bias at the outputs, eliminating the need for bulky output capacitors. The thermal  
block detects faults and shuts down the device before damage occurs. The I2C register records thermal fault  
conditions. The current limit block prevents the output current from getting high enough to damage the device.  
The De-Pop block eliminates audible pops during power-up, power-down, and amplifier enable and disable  
events.

Headphone Amplifiers  
Single-supply headphone amplifiers typically require dc-blocking capacitors. The capacitors are required  
because most headphone amplifiers have a dc bias on the outputs pin. If the dc bias is not removed, the output  
signal is severely clipped, and large amounts of dc current rush through the headphones, potentially damaging  
them. The top drawing in Figure 36 illustrates the conventional headphone amplifier connection to the  
headphone jack and output signal.  
DC blocking capacitors are often large in value. The headphone speakers (typical resistive values of 16 or 32  
) combine with the dc blocking capacitors to form a high-pass filter. Equation 1 shows the relationship between  
the load impedance (RL), the capacitor (CO), and the cutoff frequency (fC).

If fc is low, the capacitor must then have a large value because the load resistance is small. Large capacitance  
values require large package sizes. Large package sizes consume PCB area, stand high above the PCB,  
increase cost of assembly, and can reduce the fidelity of the audio output signal.  
Two different headphone amplifier applications are available that allow for the removal of the output dc blocking  
capacitors. The Capless amplifier architecture is implemented in the same manner as the conventional amplifier  
with the exception of the headphone jack shield pin. This amplifier provides a reference voltage, which is

This voltage reference is half of the amplifier power supply to allow symmetrical swing of the output voltages. Do  
not connect the shield to any GND reference or large currents will result. The scenario can happen if, for  
example, an accessory other than a floating GND headphone is plugged into the headphone connector. See the  
second block diagram and waveform in Figure 36.

Figure 36. Amplifier Applications  
The DirectPath™ amplifier architecture operates from a single supply but makes use of an internal charge pump  
to provide a negative voltage rail. Combining the user provided positive rail and the negative rail generated by  
the IC, the device operates in what is effectively a split supply mode. The output voltages are now centered at  
zero volts with the capability to swing to the positive rail or negative rail. The DirectPath™ amplifier requires no  
output dc blocking capacitors, and does not place any voltage on the sleeve. The bottom block diagram and  
waveform of Figure 36 illustrate the ground-referenced headphone architecture. This is the architecture of the  
TPA6130A2.  
Input-Blocking Capacitors  
DC input-blocking capacitors block the dc portion of the audio source, and allow the inputs to properly bias.  
Maximum performance is achieved when the inputs of the TPA6130A2 are properly biased. Performance issues  
such as pop are optimized with proper input capacitors.  
The dc input-blocking capacitors may be removed provided the inputs are connected differentially and within the  
input common mode range of the amplifier, the audio signal does not exceed ±3 V, and pop performance is  
sufficient.

CIN is a theoretical capacitor used for mathematical calculations only. Its value is the series combination of the  
dc input-blocking capacitors, C(DCINPUT-BLOCKING). Use Equation 3 to determine the value of C(DCINPUT-BLOCKING)  
.
For example, if CIN is equal to 0.22 µF, then C(DCINPUT-BLOCKING) is equal to about 0.47 µF.

The two C(DCINPUT-BLOCKING) capacitors form a high-pass filter with the input impedance of the TPA6130A2. Use  
Equation 3 to calculate CIN, then calculate the cutoff frequency using CIN and the differential input impedance of  
the TPA6130A2, RIN, using Equation 4. Note that the differential input impedance changes with gain. See  
Figure 33 for input impedance values. The frequency and/or capacitance can be determined when one of the  
two values are given.

If a high pass filter with a -3 dB point of no more than 20 Hz is desired over all gain settings, the minimum  
impedance would be used in the above equation. Figure 33 shows this to be 37 k. The capacitor value by the  
above equation would be 0.215 µF. However, this is CIN, and the desired value is for C(DCINPUT-BLOCKING)  
.
Multiplying CIN by 2 yields 0.43 µF, which is close to the standard capacitor value of 0.47 µF. Place 0.47 µF  
capacitors at each input terminal of the TPA6130A2 to complete the filter.  
Charge Pump Flying Capacitor and CPVSS Capacitor  
The charge pump flying capacitor serves to transfer charge during the generation of the negative supply voltage.  
The CPVSS capacitor must be at least equal to the flying capacitor in order to allow maximum charge transfer.  
Low ESR capacitors are an ideal selection, and a value of 1 µF is typical.  
Decoupling Capacitors  
The TPA6130A2 is a DirectPath™ headphone amplifier that requires adequate power supply decoupling to  
ensure that the noise and total harmonic distortion (THD) are low. Use good low equivalent-series-resistance  
(ESR) ceramic capacitors, typically 1.0 µF. Find the smallest package possible, and place as close as possible  
to the device VDD lead. Placing the decoupling capacitors close to the TPA6130A2 is important for the  
performance of the amplifier. Use a 10 µF or greater capacitor near the TPA6130A2 to filter lower frequency  
noise signals. The high PSRR of the TPA6130A2 will make the 10 µF capacitor unnecessary in most  
applications.  
Layout Recommendations  
Exposed Pad On TPA6130A2RTJ Package Option  
Solder the exposed metal pad on the TPA6130A2RTJ QFN package to the a pad on the PCB. The pad on the  
PCB may be grounded or may be allowed to float (not be connected to ground or power). If the pad is grounded,  
it must be connected to the same ground as the GND pins (3, 9, 10, 13, and 19). See the layout and mechanical  
drawings at the end of the datasheet for proper sizing. Soldering the thermal pad improves mechanical reliability,  
improves grounding of the device, and enhances thermal conductivity of the package.  
GND Connections  
The GND pin for charge pump should be decoupled to the charge pump VDD pin, and the GND pin adjacent to  
the Analog VDD pin should be separately decoupled to each other.  
I2C CONTROL INTERFACE DETAILS  
Addressing the TPA6130A2

TPA6130A2

SLOS488ANOVEMBER 2006REVISED DECEMBER 2006  
GENERAL I2C OPERATION  
The I2C bus employs two signals; SDA (data) and SCL (clock), to communicate between integrated circuits in a  
system. Data is transferred on the bus serially, one bit at a time. The address and data are transferred in byte  
(8-bit) format with the most-significant bit (MSB) transferred first. In addition, each byte transferred on the bus is  
acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with the master  
device driving a start condition on the bus and ends with the master device driving a stop condition on the bus.  
The bus uses transitions on the data terminal (SDA) while the clock is high to indicate start and stop conditions.  
A high-to-low transition on SDA indicates a start and a low-to-high transition indicates a stop. Normal data-bit  
transitions must occur within the low time of the clock period. These conditions are shown in Figure 37. The  
master generates the 7-bit slave address and the read/write (R/W) bit to open communication with another  
device and then wait for an acknowledge condition. The TPA6130A2 holds SDA low during acknowledge clock  
period to indicate an acknowledgment. When this occurs, the master transmits the next byte of the sequence.  
Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte). All compatible devices share  
the same signals via a bidirectional bus using a wired-AND connection.  
An external pull-up resistor must be used for the SDA and SCL signals to set the HIGH level for the bus. When  
the bus level is 5 V, pull-up resistors between 1 kand 2 kin value must be used.

Register (N)  
8- Bit Data for  
Register (N+1)  
Figure 37. Typical I2C Sequence  
There is no limit on the number of bytes that can be transmitted between start and stop conditions. When the  
last word transfers, the master generates a stop condition to release the bus. A generic data transfer sequence  
is shown in Figure 37.  
SINGLE-AND MULTIPLE-BYTE TRANSFERS  
The serial control interface supports both single-byte and multi-byte read/write operations for all registers.  
During multiple-byte read operations, the TPA6130A2 responds with data, a byte at a time, starting at the  
register assigned, as long as the master device continues to respond with acknowledges.  
The TPA6130A2 supports sequential I2C addressing. For write transactions, if a register is issued followed by  
data for that register and all the remaining registers that follow, a sequential I2C write transaction has taken  
place. For I2C sequential write transactions, the register issued then serves as the starting point, and the amount  
of data subsequently transmitted, before a stop or start is transmitted, determines to how many registers are  
written.  
SINGLE-BYTE WRITE  
As shown in Figure 38, a single-byte data write transfer begins with the master device transmitting a start  
condition followed by the I2C device address and the read/write bit. The read/write bit determines the direction of  
the data transfer. For a write data transfer, the read/write bit must be set to 0. After receiving the correct I2C  
device address and the read/write bit, the TPA6130A2 responds with an acknowledge bit. Next, the master  
transmits the register byte corresponding to the TPA6130A2 internal memory address being accessed. After  
receiving the register byte, the TPA6130A2 again responds with an acknowledge bit. Next, the master device  
transmits the data byte to be written to the memory address being accessed. After receiving the data byte, the  
TPA6130A2 again responds with an acknowledge bit. Finally, the master device transmits a stop condition to  
complete the single-byte data write transfer.

MULTIPLE-BYTE WRITE AND INCREMENTAL MULTIPLE-BYTE WRITE  
A multiple-byte data write transfer is identical to a single-byte data write transfer except that multiple data bytes  
are transmitted by the master device to the TPA6130A2 as shown in Figure 39. After receiving each data byte,  
the TPA6130A2 responds with an acknowledge bit.

Figure 39. Multiple-Byte Write Transfer  
SINGLE-BYTE READ  
As shown in Figure 40, a single-byte data read transfer begins with the master device transmitting a start  
condition followed by the I2C device address and the read/write bit. For the data read transfer, both a write  
followed by a read are actually done. Initially, a write is done to transfer the address byte of the internal memory  
address to be read. As a result, the read/write bit is set to a 0.  
After receiving the TPA6130A2 address and the read/write bit, the TPA6130A2 responds with an acknowledge  
bit. The master then sends the internal memory address byte, after which the TPA6130A2 issues an  
acknowledge bit. The master device transmits another start condition followed by the TPA6130A2 address and  
the read/write bit again. This time the read/write bit is set to 1, indicating a read transfer. Next, the TPA6130A2  
transmits the data byte from the memory address being read. After receiving the data byte, the master device  
transmits a not-acknowledge followed by a stop condition to complete the single-byte data read transfer.

SLOS488ANOVEMBER 2006REVISED DECEMBER 2006  
Modes of Operation  
The TPA6130A2 supports numerous modes of operation.  
Hardware Shutdown  
Hardware shutdown occurs when the SD pin is set to logic 0. The device is completely shutdown in this mode,  
drawing minimal current. This mode overrides all other modes. All information programmed into the registers is  
lost. When the device starts up again, the registers go back to their default state.  
Software Shutdown  
Software shutdown is set by placing a logic 1 in register 1, bit 0. That is the SWS bit. The software shutdown  
places the device in a low power state, although the current draw is higher than that of hardware shutdown (see  
the Electrical Characteristics Table for values). Engaging software shutdown turns off the charge pump and  
disables the outputs. The device is awakened by placing a logic 0 in the SWS bit.  
Note that when the device is in SWS mode, register 1, bits 7 and 6 will be cleared to reflect the disabled state of  
the amplifier. All other registers maintain their values. Re-enable the amplibifer by placing a logic 0 in the SWS  
bit. It is necessary to reset the entire register because a full word must be used when writing just one bit.  
Charge Pump Enabled, HP Amplifiers Disabled  
The output amplifiers of the TPA6130A2 are enabled by placing a logic 1 in register 1, bits 6 and 7. Place a logic  
0 in register 1, bits 6 and 7 to disable the output amplifiers. The left and right outputs can be enabled and  
disabled individually. When the output amplifiers are disabled, the charge-pump remains on.  
HiZ State  
HiZ is enabled by placing a logic 1 in register 3, bits 0 and 1. Place a logic 0 in register 3, bits 0 and 1 to disable  
the HiZ state of the outputs. The left and right outputs can be placed into a HiZ state individually.  
The HiZ state puts the outputs into a state of high impedance. Use this configuration when the outputs of the  
TPA6130A2 share traces with other devices whose outputs may be active.  
Note that to use the HiZ mode, the TPA6130A2 MUST be active (not in SWS or hardware shutdown).  
Furthermore, the output amplifiers must NOT be enabled.  
Stereo Headphone Drive  
The device is in this mode when the MODE bits in register 1 are 00 and both headphone enable bits are  
enabled. The two amplifier channels operate independently. This mode is appropriate for stereo playback.  
Dual Mono Headphone Drive  
The device is in this mode when the MODE bits in register 1 are 01 and both headphone enable bits are  
enabled. The left channel is the active input. It is amplified and distributed to both the left and right headphone  
outputs.  
Bridge-Tied Load Receiver Drive  
The device is in this mode when the MODE bits in register 1 are 10 and both headphone enable bits are  
enabled. In this mode, the device will take the left channel input and drive a single load connected between  
HPLEFT and HPRIGHT in a bridge-tied fashion. The minimum load for bridge-tied mode is the same as for  
stereo mode (see table entitled "Absolute Maximum Ratings").

Default Mode  
The TPA6130A2 starts up with the following conditions:  
SWS = Off, CHARGE PUMP = On  
HP ENABLES = Off  
HiZ = Off  
MODE = Stereo  
HP MUTES = On, VOLUME = -59.5 dB,  
VOLUME CONTROL  
The TPA6130A2 volume control is set through the I2C interface. The six volume control register bits are decoded  
to 64 volume settings that employ an audio taper. See Table 2 for the gain table. The values listed in this table  
are typical. Each gain step has a different input impedance. See Figure 33.
