Part Description

The DRV632 is a 2-VRMS pop-free stereo line driver designed to allow the removal of the output dcblocking 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 gainsetting 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. 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 require a split-rail power supply. The DRV632 integrates its own charge pump to generate a negative supply rail that provides a clean, pop-free ground-biased 2-VRMS output. The DRV632 is available in a 14-pin TSSOP.
