* These parameters are characterized but not tested.
† Data in “Typ” column is at 5V, 25C unless otherwise stated. These parameters are for design guidance only and
are not tested.
Note 1: When A/D is off, it will not consume any current other than minor leakage current.
The power-down current spec includes any such leakage from the A/D module.
2: V
REF current is from RA3 pin or VDD pin, whichever is selected as reference input.
3: The A/D conversion result never decreases with an increase in the Input Voltage and has no missing codes.
