(7) AV pin
REF
This pin inputs the A/D converter reference voltage.
It converts signals input to ANI0 to ANI7 into digital signals according to the voltage applied between AV
AV . If the voltage to be input to the AV
SS
in the series resistor string will be decreased.
Caution A series resistor string of approximately 10 k
AV
Therefore, if the output impedance of the reference voltage source is high, this will result in
parallel connection to the series resistor string between the AV
there will be a large reference voltage error.
(8) AV pin
SS
Ground potential pin of the A/D converter. It must be at the same level as the V
is not used.
(9) AV pin
DD
Analog power supply pin of the A/D converter. It must be at the same level as the V
is not used.
