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.
