9.3 PVCC, AVCC Power Supply

The TAS576xM high performance class-D audio system requires adequate power supply decoupling to ensure the output total harmonic distortion (THD) and noise is as low as possible.

Optimum decoupling is achieved by placing a good quality low equivalent-series-resistance (ESR) ceramic capacitor larger than 220nF as close to the device PVCC pins and system ground plane as possible.

For filtering lower frequency signals and handling the switching ripple current, a larger aluminum electrolytic capacitor of 470μF or greater placed near the audio power amplifier is recommended. The 470-μF capacitor also serves as a local storage capacitor for supplying current during large signal transients on the amplifier outputs.
