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.

VREF current is from GP1 pin or VDD pin, whichever is selected as reference input.

Extended operating range is Advance Information for this device.

These speciﬁcations apply if VREF = 3.0V and if VDD

≥ 3.0V. VIN must be between VSS and VREF

5: When using external VREF, VDD must be greater than 3V for +1 LSB accuracy. If VDD is less than 3V, you must

use internal VREF for +1 LSB.
