These parameters are characterized but not tested.
Data in the “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design
guidance only are not tested.
Note 1:
The A/D conversion result never decreases with an increase in the input voltage and has no missing
codes.
2:
This is the additional current consumed by the A/D module when it is enabled; this current adds to base
IDD.
