These parameters are characterized but not tested.
Data in the “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design
guidance only are not tested.
Note 1:
Total Absolute Error includes integral, differential, offset and gain errors.
2:
The A/D conversion result never decreases with an increase in the input voltage and has no missing
codes.

4:
When A/D is off, it will not consume any current other than leakage current. The power-down current
specification includes any such leakage from the A/D module.
