1.9 DIGITAL FILTER
In order to suppress erroneous remote temperature readings
due to noise as well as increase the resolution of the temper-
ature, 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.
