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.
