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 RA3 pin or V
DD
pin, whichever is selected as reference input.
These specifications apply if V
REF
= 3.0V and if V
DD
3.0V. V
AIN
must be between V
SS
and V
REF
.
