In order to suppress erroneous remote temperature readings
due to noise, the LM99 incorporates a user-configured digital
filter. The filter is accessed in the FILTER and ALERT CON-
FIGURE REGISTER at BFh. The filter can be set according
to the table shown.
Level 2 sets maximum filtering.
Figure 8
depict the filter output to in response to a step input
and an impulse input.
Figure 9
depicts the digital filter in use
in a Pentium 4 processor system. Note that the two curves,
with filter and without, have been purposely offset so that
both responses can be clearly seen. Inserting the filter does
not induce an offset as shown.
