11 Power Supply Recommendations

The TAS5729MD requires two power supplies; a low-voltage 3.3-V nominal for the pins DVDD, AVDD, and DRVDD and a high-voltage power supply, 4.5 V to 26 V for the pin PVDD. The low-voltage and high-voltage power supplies have no required sequencing for power-up; however, the PDN pin should be put to low before removing the low-voltage power supplies to protect the outputs.

11.1 DVDD, AVDD, and DRVDD Supplies

The AVDD supply is used to power the analog internal circuit of the device, and requires a well-regulated and filtered 3.3-V supply voltage. The DVDD supply is used to power the digital circuitry, and also requires a well-regulated and filtered 3.3-V supply voltage. The DRVDD supply is used to power the DirectPath™ headphone/line driver.

11.2 PVDD Power Supply

The TAS5729MD 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, a 10-µF or greater capacitor placed near the audio power amplifier is recommended.
