PRODUCTION DATA.
The TAS5806MD device requires three power supplies for proper operation. A high-voltage supply calls PVDD is required to power the output stage of the speaker amplifier and its associated circuitry. One low-voltage power supply which is calls DVDD is required to power the various low-power portions of the device. Another low-voltage power supply which is calls HPVDD for headphone driver. The allowable voltage range for both PVDD, DVDD and HPVDD supply are listed in the Recommended Operating Conditions table. The two power supplies do not have a required power-up sequence. The power supplies can be powered on in any order. But once the device has been initialized, PVDD must keep within the normal operation voltage. Once PVDD lower than 3.5V, all registers need re-initialize again.
