Sample time and conversion time of the C164CI
s A/D Converter are programmable.
Table 14
should be used to calculate the above timings.
The limit values for

During the sample time the input capacitance
C
AIN
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 time
t
S
depend on programming and can be taken from
