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.

2: VREF current is from External VREF+, OR VREF-, or AVSS, or AVDD 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.
