sampling time is 4 to 24 adc clock cycles of
0.25MHz to 8MHz -> 96
 s >= tsample >= 500ns
Switch resistance depends on input voltage, corner ranges are shown.
Leakage current is guaranteed by specification.
Complete 10bit conversion takes between 19 and 41 adc clock cycles

potential just prior to sampling is either
a) ~ last converted channel potential or
b) ground level if S/H discharge feature is enabled.
