(1) _{During the sample time the input capacitance CAIN (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 t_S. After the end of the sample time t_S,
changes of the analog input voltage have no effect on the conversion result. Values for the
sample clock t_S depend on programming.
