LM34/LM34A/LM34C/LM34CA/LM34D  
Precision Fahrenheit Temperature Sensors  
General Description  
The LM34 series are precision integrated-circuit tempera-  
ture sensors, whose output voltage is linearly proportional to  
the Fahrenheit temperature. The LM34 thus has an advan-  
tage over linear temperature sensors calibrated in degrees  
Kelvin, as the user is not required to subtract a large con-  
stant voltage from its output to obtain convenient Fahren-  
heit scaling. The LM34 does not require any external cali-  
while the LM34C, LM34CA and LM34D are also available in  
the plastic TO-92 transistor package. The LM34D is also  
available in an 8-lead surface mount small outline package.  
The LM34 is a complement to the LM35 (Centigrade) tem-  
perature sensor.

temperature range. Low cost is assured by trimming and  
calibration at the wafer level. The LM34’s low output imped-  
ance, linear output, and precise inherent calibration make  
interfacing to readout or control circuitry especially easy. It  
can be used with single power supplies or with plus and  
minus supplies. As it draws only 75 mA from its supply, it has
