During the sample time, the sampling capacitance, Csamp (3 pF typ), 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 tS. After the end of the sample time tS, changes of the analog input voltage have no
effect on the conversion result.
