* These parameters are characterized but not tested.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not

tested.

Note 1:Total Absolute Error includes integral, differential, offset and gain errors.

2: The ADC conversion result never decreases with an increase in the input voltage and has no missing codes.

3: See Section 29.0 “DC and AC Characteristics Graphs and Charts” for operating characterization.

4: ADC VREF is selected by ADPREF<0> bit.
