What the DirectPath series means for your audio output stage
The DRV602PW is a Class AB stereo line driver from TI's DirectPath series — the architecture eliminates the large DC-blocking output capacitors that conventional headphone or line-out stages need, saving board space and BOM cost in portable and consumer audio gear. It runs from a single 3V to 5.5V supply rail, so it fits battery-powered devices (Li-ion at 3.6V nominal) and regulated 3.3V or 5V audio subsystems without a split supply.
Package, temperature grade, and integration checklist
The built-in depop circuitry suppresses turn-on/turn-off clicks, and the differential inputs reject common-mode noise picked up on long PCB traces or ribbon cables between the codec and the amplifier.
