NOTES:

1 V

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

2 Analog and digital V

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

3 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

4 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.

5 The maximum sample rate is 1 million samples per second, provided the source impedance and current

limiter(>1 k

) are calculated adequately.

- Filter capacitor at analog source output must meet the criteria Cf (filter capacitor) > 2048*Cs (sampling capacitor

which is 3 pF)

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.
