FEATURES  
DESCRIPTION  
The DRV632 is a 2-VRMS pop-free stereo line driver  
designed to allow the removal of the output dc-  
blocking capacitors for reduced component count and  
cost. The device is ideal for single-supply electronics  
where size and cost are critical design parameters.

Designed  
using  
TI’s  
patented  
DirectPath™  
technology, The DRV632 is capable of driving 2 VRMS  
into a 10-kΩ load with 3.3-V supply voltage. The  
device has differential inputs and uses external gain-  
setting resistors to support a gain range of ±1 V/V to  
±10 V/V, and gain can be configured individually for  
each channel. Line outputs have ±8-kV IEC ESD  
protection, requiring just a simple resistor-capacitor  
ESD protection circuit. The DRV632 has built-in  
active-mute control for pop-free audio on/off control.  
The DRV632 has an external undervoltage detector  
that mutes the output when the power supply is  
removed, ensuring a pop-free shutdown.

Response Due to Output Capacitors  
Using the DRV632 in audio products can reduce  
component count considerably compared to  
traditional methods of generating a 2-VRMS output.  
The DRV632 does not require a power supply greater  
than 3.3 V to generate its 5.6-Vpp output, nor does it

ground-biased 2-VRMS output.
