Remote temperature data with the digital filter on is repre-
sented by a 13-bit, two’s complement word or unsigned
binary word with an LSb (Least Significant Bit) equal to
0.03125˚C (1/32˚C). The data format is a left justified 16-bit
word available in two 8-bit registers. Unused bits will always
report "0".

Local Temperature data is represented by a 10-bit, two’s
complement word with an LSb (Least Significant Bit) equal to
0.25˚C. The data format is a left justified 16-bit word avail-
able in two 8-bit registers. Unused bits will always report "0".
Local temperature readings greater than +127.875˚C are
clamped to +127.875˚C, they will not roll-over to negative
temperature readings.

1.5 SMBDAT OPEN-DRAIN OUTPUT
The SMBDAT output is an open-drain output and does not
have internal pull-ups. A “high” level will not be observed on
this pin until pull-up current is provided by some external
source, typically a pull-up resistor. Choice of resistor value
depends on many system factors but, in general, the pull-up
resistor should be as large as possible without effecting the
SMBus desired data rate. This will minimize any internal
temperature reading errors due to internal heating of the
LM95241. The maximum resistance of the pull-up to provide
a 2.1V high level, based on LM95241 specification for High
Level Output Current with the supply voltage at 3.0V, is
82k
Ω(5%) or 88.7kΩ(1%).
1.6 DIODE FAULT DETECTION
The LM95241 is equipped with operational circuitry designed
to detect fault conditions concerning the remote diodes. In
the event that the D+ pin is detected as shorted to GND, D−,
V
DD or D+ is floating, the Remote Temperature reading is
–128.000 ˚C if signed format is selected and +255.875 if
unsigned format is selected. In addition, the appropriate
status register bits RD1M or RD2M (D1 or D0) are set.
1.7 COMMUNICATING WITH THE LM95241
The data registers in the LM95241 are selected by the
Command Register. At power-up the Command Register is
set to “00”, the location for the Read Local Temperature
Register. The Command Register latches the last location it
was set to. Each data register in the LM95241 falls into one
of four types of user accessibility:
