The DRV603PW is a 3-V_RMS 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 DRV603 is capable of driving 3 V_rms into a 2.5-k load with 5-V supply voltage. The device has differential inputs and uses external gain-setting resistors to support a gain range of ±1 V/V to ±10 V/V, and line outputs that have ±8 kV IEC ESD protection. The DRV603 (occasionally referred to as the ‘603) has built-in shutdown control for pop-free on/off control. The DRV603 has an external and internal undervoltage detector that mutes the output.

Using the DRV603 in audio products can reduce component count considerably compared to traditional methods of generating a 3-V_rms output. The DRV603 does not require a power supply greater than 5 V to generate its 8.5-V_pp output, nor does it require a split-rail power supply. The DRV603 integrates its own charge pump to generate a negative supply rail that provides a clean, pop-free ground biased 3-V_rms output.

The DRV603 is available in a 14-pin TSSOP.

If the low noise and trimmed dc-offset and external undervoltage mute function are not beneficial in the application, TI recommends the footprint compatible DRV602.
