The LM50 is a precision integrated-circuit temperature sen-  
sor that can sense a −40˚C to +125˚C temperature range us-  
ing a single positive supply. The LM50’s output voltage is lin-  
early proportional to Celsius (Centigrade) temperature  
(+10 mV/˚C) and has a DC offset of +500 mV. The offset al-  
lows reading negative temperatures without the need for a  
negative supply. The ideal output voltage of the LM50 ranges  
from +100 mV to +1.75V for a −40˚C to +125˚C temperature  
range. The LM50 does not require any external calibration or  
±
trimming to provide accuracies of 3˚C at room temperature  
±
and 4˚C over the full −40˚C to +125˚C temperature range.  
Trimming and calibration of the LM50 at the wafer level as-  
sure low cost and high accuracy. The LM50’s linear output,  
+500 mV offset, and factory calibration simplify circuitry re-  
quired in a single supply environment where reading nega-  
tive temperatures is required. Because the LM50’s quiescent  
current is less than 130 µA, self-heating is limited to a very  
low 0.2˚C in still air.  
Features  
n Calibrated directly in degree Celsius (Centigrade)  
n Linear + 10.0 mV/˚C scale factor  
±
n
2˚C accuracy guaranteed at +25˚C  
n Specified for full −40˚ to +125˚C range  
n Suitable for remote applications  
n Low cost due to wafer-level trimming  
n Operates from 4.5V to 10V  
n Less than 130 µA current drain  
n Low self-heating, less than 0.2˚C in still air  
n Nonlinearity less than 0.8˚C over temp
