ZHCSGH3A March 2016 – July 2017 TAS5782M
PRODUCTION DATA.
The TAS5782M device requires two power supplies for proper operation. A high-voltage supply called PVDD is required to power the output stage of the speaker amplifier and its associated circuitry. Additionally, one low-voltage power supply which is called DVDD is required to power the various low-power portions of the device. The allowable voltage range for both the PVDD and the DVDD supply are listed in the Recommended Operating Conditions table. The two power supplies do not have a required powerup sequence. The power supplies can be powered on in any order. TI recommends waiting 100 ms to 240 ms for the DVDD power supplies to stabilize before starting I2C communication and providing stable I2S clock before enabling the device outputs.
