DRV632PW Line Driver

Texas Instruments' DirectPath™, 2 VRMS line driver with adjustable gain

Texas Instruments DRV632PW Line Driver Texas Instruments' 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.   DRV632 Datasheet
