All other times
These parameters are characterized but not tested.
Data in 鈥淭yp鈥?column is at 5V, 25掳C unless otherwise stated. These parameters are for design guidance only and are not
tested.
Note 1: These speci铿乧ations apply if V

= 3.0V and if V

3.0V. V

must be between V
SS
and V
REF
2: 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.
3: V
REF
current is from GP1 pin or V
DD
pin, whichever is selected as reference input.
4: When using external V
REF
, V
DD
must be greater than 3V for +1 LSB accuracy. If V
DD
is less than 3V, you
must use internal V
REF
for +1 LSB.
