FEATURES  
DESCRIPTION  
The LM50/LM50-Q1 is a precision integrated-circuit  
temperature sensor that can sense a −40°C to  
+125°C temperature range using a single positive  
supply. The LM50/LM50-Q1's output voltage is  
linearly proportional to Celsius (Centigrade)  
temperature (+10 mV/°C) and has a DC offset of  
+500 mV. The offset allows reading negative  
temperatures without the need for a negative supply.  
The ideal output voltage of the LM50/LM50-Q1  
ranges from +100 mV to +1.75V for a −40°C to  
+125°C temperature range. The LM50/LM50-Q1 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/LM50-  
Q1 at the wafer level assure low cost and high  
accuracy. The LM50/LM50-Q1's linear output, +500  
mV offset, and factory calibration simplify circuitry  
required in a single supply environment where  
reading negative temperatures is required. Because  
the LM50/LM50-Q1's quiescent current is less than  
130 μA, self-heating is limited to a very low 0.2°C in  
still air.
