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.
V
REF
current is from the RA3 pin or the V
DD
pin, whichever is selected as a reference input.
The A/D conversion result never decreases with an increase in the input voltage and has no missing
codes.
