– 3 Vrms With 5-V Supply Voltage Differential Input External Undervoltage Mute The DRV603PW is a 3-VRMS 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. 1 234 Using the DRV603 in audio products can reduce
component count considerably compared to
traditional methods of generating a 3-Vrms output. The
DRV603 does not require a power supply greater
than 5 V to generate its 8.5-Vpp output, nor does it
require a split-rail power supply. The DRV603
integrates its own charge pump to generate a …
