SNIS143E – AUGUST 2006 – REVISED MARCH 2013
DESCRIPTION (CONTINUED)
The LM95241 resolution format for remote temperature readings can be programmed to be 11-bits signed or
unsigned with the digital filtering disabled. When the filtering is enabled the resolution increases to 13-bits signed
or unsigned. In the unsigned mode the LM95241 remote diode readings can resolve temperatures above 127°C.
Local temperature readings have a resolution of 9-bits plus sign.

Typical Connection
To Diode Anode. Connected to remote discrete diode-
connected transistor junction or to the diode-connected
transistor junction on a remote IC whose die temperature is
being sensed. A capacitor is not required between D1+ and
D1-. A 100 pF capacitor between D1+ and D1 ? can be added
and may improve performance in noisy systems.

DC Voltage from 3.0 V to 3.6 V. V DD should be bypassed with
a 0.1 μF capacitor in parallel with 100 pF. The 100 pF
capacitor should be placed as close as possible to the power
supply pin. Noise should be kept below 200 mVp-p, a 10 μF
capacitor may be required to achieve this.
