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 V
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.
