Input Signal Filtering and Averaging
Input signal filtering and averaging is configured in the calibra-
tion mode. Programmable averaging allows you to program the
number of samples you want to average the input signal over
(from 1 to 255 samples).
A programmable averaging window provides a quick response
time to large input signal changes. The averaging window can
be set to between 1 and 65535 counts.
