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_ADC1 and VDD_ADC1 limits, remaining on absolute maximum ratings, but the results of the

conversion will be clamped respectively to 0x000 or 0xFFF.

4 During the sampling 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 tADC1_S. After the end

of the sampling time tADC1_S, changes of the analog input voltage have no effect on the conversion result. Values for

the sampling clock tADC1_S depend on programming.

5 This parameter does not include the sampling time t

ADC1_S, but only the time for determining the digital result and the

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

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

internal divider by 2.

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.
