Current consumption
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.
