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. The DRV604 has built-in enable control for pop-free on/off control. DRV604 can monitor an external supply voltage using its built in comparator enabling it to shut down during a brown out condition before up stream audio DAC’s can produce click and pop artifacts.
Using the DRV604 in audio products can reduce component count considerably compared to traditional methods of generating headphone output and 2Vrms output. The DRV604 does not require a power supply greater than 3.3V to generate its 5.6Vpp output, nor does it require a split rail power supply. The DRV604 integrates its own charge pump to generate a negative supply rail that provides a clean, pop-free ground biased 2Vrms output.
The DRV604 is available in a 28-pin HTSSOP. For a stereo line driver with no HP amp see DRV603.
