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.

This is the additional current consumed by the A/D module when it is enabled; this current adds to base

IDD.
