1.4 TEMPERATURE CONVERSION SEQUENCE
Each of the 3 temperature channels of LM95213 can be
turned OFF independent from each other via the Channel
Enable Register. Turning off unused channels will increase
the conversion speed in the fastest conversion speed mode.
If the slower conversion speed settings are used, disabling
unused channels will reduce the average power consumption
of LM95213.
1.5 DIGITAL FILTER
In order to suppress erroneous remote temperature readings
due to noise as well as increase the resolution of the temper-
ature, the LM95213 incorporates a digital filter for Remote 1
and 2 Temperature Channels. When a filter is enabled the
filtered readings are used for the TCRIT comparisons. There
are two possible digital filter settings that are enabled through
the Filter Setting Register at register address 0Fh. The filter
for each channel can be set according to the following table:
R1F[1:0] or R2F[1:0]

describes the filter output in response to a step input
and an impulse input.

b) Impulse response with input
transients less than 4°C
c) Impulse response with input
transients great than 4°C

clarity.
Figure 3
shows the filter in use in a typical processor system.
Note that the two curves have been purposely offset for clar-
ity. Inserting the filter does not induce an offset as shown.
1.6 TEMPERATURE DATA FORMAT
Temperature data can only be read from the Local and Re-
mote Temperature value registers. The data format for all
temperature values is left justified 16-bit word available in two
8-bit registers. Unused bits will always report "0". All temper-
ature data is clamped and will not roll over when a tempera-
ture exceeds full-scale value.
Remote temperature data for all channels can be represented
by an 11-bit, two's complement word or unsigned binary word
with an LSb (Least Significant Bit) equal to 0.125°C.
