SLOSE75B February 2022 – March 2023 TAS2780
PRODUCTION DATA
The TAS2780 can operate with or without an external VBAT1S supply. When configured without an external VBAT1S supply, the PVDD voltage will be used with an internal LDO to generate this supply voltage. A decoupling capacitor should still be populated as recommended in Table 9-1. In this case, VBAT1S_MODE bit should be set to high before transitioning from software shutdown. More details about VBAT1S supply modes of operation can be found in Section 11.1.
