Current consumption

2. Analog and digital VSS must be common (to be tied together externally).

3. VAINx may exceed VSS_ADC and VDD_ADC limits, remaining on absolute maximum ratings, but the results of the conversion

will be clamped respectively to 0x000 or 0xFFF.

4. Duty cycle is ensured by using system clock without prescaling. When ADCLKSEL = 0, the duty cycle is ensured by internal

divider by 2.

5. During the sampling time the input capacitance CS can be charged/discharged by the external source. The internal

resistance of the analog source must allow the capacitance to reach its final voltage level within tS. After the end of the

sampling time tS, changes of the analog input voltage have no effect on the conversion result. Values for the sample clock

tS depend on programming.

6. This parameter does not include the sampling time tS, but only the time for determining the digital result and the time to load

the result’s register with the conversion result.
