DRV604 DirectPath'tm' 2Vrms Line driver & HP amp w. adjustable gain

The DRV604 is a 2Vrms Pop-Free stereo line driver with stereo headphone output 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 DRV604 is capable of driving 2 Vrms into a 5k load. The headphone output can generate a clean 40mW into 32 load from a 3.3V supply. The device has differential inputs and uses external gain setting resistors that supports a gain range of –1V/V to –10V/V. Headphone and line outputs have ±8kV IEC ESD protection enabling a simple ESD protection circuit
