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.
