†Data in “Typ” column is at 5.0V, 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 or VDD pin, 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.
