12 Power Supply Recommendations

The TAS5727 requires two power supplies: a low voltage, 3.3 V nominal for the pins DVDD, AVDD, and DRVDD, and a high power supply of 8 V to 24 V for the pin PVDD. There is no requirement for power-up sequencing of low and high power supplies; however, TI recommends putting the PDN pin to low before removing the low voltage power supplies to protect the outputs.

12.1 DVDD and AVDD Supplies

The AVDD Supply is used to power the analog internal circuit of the device, and needs a well-regulated and filtered 3.3-V supply voltage. The DVDD Supply is used to power the digital circuitry. DVDD needs a well-regulated and filtered 3.3-V supply voltage.

12.2 PVDD Power Supply

The TAS5727 class-D audio amplifier requires adequate power supply decoupling to ensure the output total harmonic distortion (THD) and noise is as low as possible. A good low equivalent-series-resistance (ESR) ceramic capacitor, typically 1 µF, placed as close as possible to the device PVDD leads works best. For filtering lower-frequency noise signals, TI recommends placing a 10 µF or greater capacitor near the audio power amplifier.
