During A/D

Conversion cycle

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.

VREF current is from RA3 pin or VDD pin, whichever is selected as reference input.

The A/D conversion result never decreases with an increase in the input voltage, and has no missing

codes.
