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: VREF 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.
