Note 1:

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.

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 RG0 and RG1 pins or AVDD and AVSS pins, whichever is selected as reference input.
