Function
Power supply for the A/D converter. Connect
this pin as close as possible to the V_CC pin and at
the same voltage as V_CC. If the power supply
voltage to be used for the A/D converter is not
equal to V_CC, connect a 0.1-µF bypass capacitor
between the AV_CC and AV_SS pins. (However, this
is not necessary when the AV_CC pin is directly
connected to the V_CC pin.)
Ground for the A/D converter. Connect this pin
as close as possible to GND at the same voltage
as GND.
