DVDD PWR
-
Connect this pin to a 2.6 to 5.5V power supply. Connect a
bypass capacitor of 0.1μF or greater between this pin and the
VSS pin.
11
VSS PWR
-
VSS power supply pin
Always apply a voltage of 0V to this pin.
Analog VDD power supply pin
Connect this pin to a 2.6 to 5.5V power supply. Connect a
12
AVDD PWR
-
bypass capacitor of 0.1μF or greater between this pin and the
VSS pin.
Apply a voltage so that DVDD is equal to or less than AVDD.
