1.9 DIGITAL FILTER
In order to suppress erroneous remote temperature readings due to noise as well as increase the resolution of the temperature,
the LM96163 incorporates a digital filter for remote temperature readings. The filter is accessed in the Remote Diode Temperature
Filter and Comparator Mode Register. The filter can be set according to the following table.
