APPLICATION INFORMATION
LINE DRIVER AMPLIFIERS
Single-supply line-driver amplifiers typically require dc-blocking capacitors. The top drawing in Figure 6 illustrates
the conventional line-driver amplifier connection to the load and output signal. DC blocking capacitors are often
large in value. The line load (typical resistive values of 600 Ω to 10 kΩ) combines 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).
1
fc =
2pRLCO
(1)
CO can be determined using Equation 2, where the load impedance and the cutoff frequency are known.
1
CO
=
2pRLfc
(2)
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.

Figure 6. Conventional and DirectPath Line Drivers
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. Combining this with the built-in click and pop
reduction circuit, the DirectPath amplifier requires no output dc blocking capacitors. The bottom block diagram
and waveform of Figure 6 illustrate the ground-referenced line-driver architecture. This is the architecture of the
DRV632.

CHARGE-PUMP FLYING CAPACITOR AND PVSS CAPACITOR
The charge-pump flying capacitor serves to transfer charge during the generation of the negative supply voltage.
The PVSS capacitor must be at least equal to the charge-pump capacitor in order to allow maximum charge
transfer. Low-ESR capacitors are an ideal selection, and a value of 1 mF is typical. Capacitor values that are
smaller than 1 mF can be used, but the maximum output voltage may be reduced and the device may not
operate to specifications. If the DRV632 is used in highly noise-sensitive circuits, it is recommended to add a
small LC filter on the VDD connection.
DECOUPLING CAPACITORS
The DRV632 is a DirectPath line-driver amplifier that requires adequate power supply decoupling to ensure that
the noise and total harmonic distortion (THD) are low. A good, low equivalent-series-resistance (ESR) ceramic
capacitor, typically 1 mF, placed as close as possible to the device VDD lead works best. Placing this decoupling
capacitor close to the DRV632 is important for the performance of the amplifier. For filtering lower-frequency
noise signals, a 10-mF or greater capacitor placed near the audio power amplifier would also help, but it is not
required in most applications because of the high PSRR of this device.
GAIN-SETTING RESISTOR RANGES
The gain-setting resistors, RIN and Rfb, must be chosen so that noise, stability, and input capacitor size of the
DRV632 are kept within acceptable limits. Voltage gain is defined as Rfb divided by RIN.
Selecting values that are too low demands a large input ac-coupling capacitor, CIN. Selecting values that are too
high increases the noise of the amplifier. Table 1 lists the recommended resistor values for different
inverting-input gain settings.

USING THE DRV632 AS A SECOND-ORDER FILTER
Several audio DACs used today require an external low-pass filter to remove out-of-band noise. This is possible
with the DRV632, as it can be used like a standard operational amplifier. Several filter topologies can be
implemented, both single-ended and differential. In Figure 7, multi-feedback (MFB) with differential input and
single-ended input are shown.
An ac-coupling capacitor to remove dc content from the source is shown; it serves to block any dc content from
the source and lowers the dc gain to 1, helping to reduce the output dc offset to a minimum.
The component values can be calculated with the help of the TI FilterPro™ program available on the TI Web site
at:
http://focus.ti.com/docs/toolsw/folders/print/filterpro.html.

Figure 7. Second-Order Active Low-Pass Filter
The resistor values should have a low value for obtaining low noise, but should also have a high enough value to
get a small-size ac-coupling capacitor. With the proposed values of R1 = 15 kΩ, R2 = 30 kΩ, and R3 = 43 kΩ, a
dynamic range (DYR) of 106 dB can be achieved with a 1-mF input ac-coupling capacitor.
INPUT-BLOCKING CAPACITORS
DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the
DRV632. These capacitors block the dc portion of the audio source and allow the DRV632 inputs to be properly
biased to provide maximum performance.
These capacitors form a high-pass filter with the input resistor, RIN. The cutoff frequency is calculated using
Equation 3. For this calculation, the capacitance used is the input-blocking capacitor, and the resistance is the
input resistor chosen from Table 1; then the frequency and/or capacitance can be determined when one of the
two values is given.
It is recommended to use electrolytic capacitors or high-voltage-rated capacitors as input blocking capacitors to
ensure minimal variation in capacitance with input voltages. Such variation in capacitance with input voltages is
commonly seen in ceramic capacitors and can increase low-frequency audio distortion.

DRV632 UVP OPERATION
The shutdown threshold at the UVP pin is 1.25 V. The customer must use a resistor divider to obtain the
shutdown threshold and hysteresis desired for a particular application. The customer-selected thresholds can be
determined as follows:
EXTERNAL UNDERVOLTAGE DETECTION
External undervoltage detection can be used to mute/shut down the DRV632 before an input device can
generate a pop.
The shutdown threshold at the UVP pin is 1.25 V. The user selects a resistor divider to obtain the shutdown
threshold and hysteresis for the specific application. The thresholds can be determined as follows:
VUVP = (1.25 – 6 mA × R3) × (R1 + R2) / R2
Hysteresis = 5 mA × R3 × (R1 + R2) / R2
For example, to obtain VUVP = 3.8 V and 1-V hysteresis, we can use R1 = 3 kΩ, R2 = 1 kΩ, and R3 = 50 kΩ.

LAYOUT RECOMMENDATIONS
A proposed layout for the DRV632 can be seen in the DRV632EVM User's Guide, and the Gerber files can be
downloaded from http://www.ti.com. To access this information, open the DRV632 product folder and look in the
Tools and Software folder.
GAIN-SETTING RESISTORS
The gain-setting resistors, RIN and Rfb, must be placed close to pins 13 and 17, respectively, to minimize
capacitive loading on these input pins and to ensure maximum stability of the DRV632. For the recommended
PCB layout, see the DRV632EVM User's Guide.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
