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.
Total Absolute Error includes integral, differential, offset and gain errors.
The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
ADC VREF is from external VREF, VDD pin or FVR, whichever is selected as reference input.
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.
FVR voltage selected must be 2.048V or 4.096V.
