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 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.
