The LM61 is a precision integrated-circuit temperature sen-  
sor that can sense a −30˚C to +100˚C temperature range  
while operating from a single +2.7V supply. The LM61’s out-  
put voltage is linearly proportional to Celsius (Centigrade)  
temperature (+10 mV/˚C) and has a DC offset of +600 mV.  
The offset allows reading negative temperatures without the  
need for a negative supply. The nominal output voltage of the  
LM61 ranges from +300 mV to +1600 mV for a −30˚C to  
+100˚C temperature range. The LM61 is calibrated to pro-  
±
±
vide accuracies of 2.0˚C at room temperature and 3˚C  
over the full −25˚C to +85˚C temperature range.  
Key Specifications  
The LM61’s linear output, +600 mV offset, and factory cali-  
bration simplify external circuitry required in a single supply  
environment where reading negative temperatures is re-  
quired. Because the LM61’s quiescent current is less than  
125 µA, self-heating is limited to a very low 0.2˚C in still air.  
Shutdown capability for the LM61 is intrinsic because its in-  
herent low power consumption allows it to be powered di-  
rectly from the output of many logic gates.
