Analog switch booster
5.3.21
12-bit Analog-to-Digital converter (ADC4) characteristics
Unless otherwise specified, the parameters given in the following tables are derived at
ambient temperature, and under the fHCLK frequency and supply voltage conditions
summarized in Table 26.
Note:
It is recommended to perform a calibration after each power-up.
