Texas Instruments DRV602PWR
The DRV602PW is a 3Vrms 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 TIs patented DirectPath™ technology, the DRV602 is capable of driving 3Vrms into a 2.5k load with 5V supply voltage. The device has differential inputs and uses external gain setting resistors, that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd order low pass filter to compliment DACs and SOC converters. The line output of the DRV602 has ±8kV IEC ESD protection. The DRV602 (referred to as the 602) has built-in shutdown control for pop-free on/off control.
Using the DRV602 in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The DRV602 doesn't require a power supply greater than 5V to generate its 8.5VPP output, nor does it require a split rail power supply. The DRV602 integrates its own charge pump to generate a negative supply rail that provides a clean, pop-free ground biased 3Vrms output.
The DRV602 is available in a 14 pin TSSOP package.
If higher SNR, trimmed DC-offset and external undervoltage-mute functions are beneficial in the application, TI recommends the footprint compatible DRV603 (SLOS617).
For a stereo line and stereo HP driver see DRV604 (SLOS659).
