(1) During the sample time the input capacitance C

AIN (3 pF max) 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. Values for the

sample clock tS depend on programming.
