PRODUCTION DATA.
The TAS5806M device requires two 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. The allowable voltage range for both PVDD and DVDD supply are listed in the Recommended Operating Conditions table. These 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. Recommends waiting 1 ms to 5 ms for the DVDD power supplies to stabilize before starting I2C communication and providing stable I2S clock before enabling the device outputs.
