Power supply for the A/D converter. Connect this pin
as close as possible to the V
pin and at the same
voltage as V
. If the power supply voltage to be used
for the A/D converter is not equal to V
CC
, connect a 0.1-
μ
F bypass capacitor between the AV
and AV
pins.
(However, this is not necessary when the AV
CC
pin is
directly connected to the V

pin.)
Ground for the A/D converter. Connect this pin as
close as possible to GND at the same voltage as GND.
