12 Power Supply Recommendations

The TAS6422-Q1 requires three power supplies. The PVDD supply is the high-current supply in the recommended supply range. The VBAT supply is lower current supply that must be in the recommended supply range. The PVDD and VBAT pins can be connected to the same supply if the recommended supply range for VBAT is maintained. The VDD supply is the 3.3 Vdc logic supply and must be maintained in the tolerance as shown in the Recommended Operating Conditions table.
