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:
V
REF
current is from RA3 pin or V
DD
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.
