27.6.1 Principle of Operation

By default, the ADC provides results with 12-bit resolution. The 8-bit or 10-bit results can be selected in order to reduce the conversion time.

The ADC has an oversampling with decimation option that can extend the resolution to 16-bits. The input values can be either internal (e.g., internal temperature sensor) or external (connected I/O pins). The user can also configure whether the conversion should be single-ended or differential.
