1 V

DD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified.

2 Analog and digital V

SS must be common (to be tied together externally).

3 V

AINx 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 sample time the input capacitance C

S 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 tADC_S. After the

end of the sample time tADC_S, changes of the analog input voltage have no effect on the conversion result. Values

for the sample clock tADC_S depend on programming.

6 This parameter does not include the sample time t

ADC_S, but only the time for determining the digital result and the

time to load the result’s register with the conversion result.

7 Total Unadjusted Error: The maximum error that occurs without adjusting Offset and Gain errors. This error is a

combination of Offset, Gain and Integral Linearity errors.
