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 TI?s 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 DAC?s 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).
