1. Data guaranteed by design, not tested in production..

2. 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 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.
