LM35 Precision Centigrade Temperature Sensors

FEATURES  
DESCRIPTION  
The LM35 series are precision integrated-circuit  
2
Calibrated Directly in ° Celsius (Centigrade)  
Linear + 10 mV/°C Scale Factor  
temperature sensors, with an output voltage linearly  
proportional to the Centigrade temperature. Thus the  
LM35 has an advantage over linear temperature  
sensors calibrated in ° Kelvin, as the user is not  
required to subtract a large constant voltage from the  
output to obtain convenient Centigrade scaling. The  
LM35 does not require any external calibration or  
trimming to provide typical accuracies of ±¼°C at  
room temperature and ±¾°C over a full 55°C to  
+150°C temperature range. Low cost is assured by  
trimming and calibration at the wafer level. The low  
output impedance, linear output, and precise inherent  
calibration of the LM35 make interfacing to readout or  
control circuitry especially easy. The device is used  
with single power supplies, or with plus and minus  
supplies. As the LM35 draws only 60 μA from the  
supply, it has very low self-heating of less than 0.1°C  
in still air. The LM35 is rated to operate over a 55°C  
to +150°C temperature range, while the LM35C is  
rated for a 40°C to +110°C range (10° with  
improved accuracy). The LM35 series is available  
packaged in hermetic TO transistor packages, while  
the LM35C, LM35CA, and LM35D are also available  
in the plastic TO-92 transistor package. The LM35D  
is also available in an 8-lead surface-mount small-  
outline package and a plastic TO-220 package.
