2.4.8 Class-D Amplifier

This reference design supports 4-zone audio output with the TPA6304-Q1 four-channel Class-D Burr-Brown audio amplifier. This reference design supports single zone audio output for warning chimes with a TAS6421 Class-D amplifier. Both devices implement a 2.1 MHz PWM switching frequency that enables a cost optimized solution in a very small PCB footprint while offering exceptional sound quality with up to 40 kHz audio bandwidth.
