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 A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
3: ADC VREF is from external VREF, VDD pin or FVR, whichever is selected as reference input.
4: When ADC is off, it will not consume any current other than leakage current. The power-down current specification
includes any such leakage from the ADC module.
5: FVR voltage selected must be 2.048V or 4.096V.
