1 V

DDA = 3.3 V ± 10% / 5.0 V ± 10%, TA = -40 to +105 °C, unless otherwise specified.

2 All values need to be confirmed during device validation.

3 Analog and digital V

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

4 V

AINx may exceed VSSA and VDDA limits, remaining on absolute maximum ratings, but the results of the conversion will be

clamped respectively to 0x000 or 0x3FF.

5 Guaranteed by design.

6 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.

7 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.
