Power Supply Unit
own power supplies to allow exceptional audio quality.
Battery Supply Voltage (VBAT)
is VBAT. It is typically 1.8 V. The WLCSP package option
is also using VBAT to define the I/O voltage levels, as well
as powering an external EEPROM on the SPI port.
Consequently, any voltage below 1.8 V will result in
BelaSigna 300 has multiple power sources as can be seen on Figure 13. Digital and analog sections of the chip have their

incorrect operation of the EEPROM. On the DFN package
option, the above connection doesn’t exist, so the voltage on
VBAT can be safely used down to its minimum value of
1.25 V.
