FEATURES  
DESCRIPTION  
The LM61 is  
a
precision integrated-circuit  
2
Calibrated Linear Scale Factor of +10 mV/°C  
Rated for Full 30° to +100°C Range  
Suitable for Remote Applications  
UL Recognized Component  
temperature sensor that can sense a 30°C to  
+100°C temperature range while operating from a  
single +2.7V supply. The LM61's output 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 provide  
accuracies of ±2.0°C at room temperature and ±3°C  
over the full 25°C to +85°C temperature range.  
APPLICATIONS  
Cellular Phones  
Computers  
Power Supply Modules  
Battery Management  
FAX Machines  
Printers  
The LM61's linear output, +600 mV offset, and factory  
calibration simplify external circuitry required in a  
single supply environment where reading negative  
temperatures is required. 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  
inherent low power consumption allows it to be  
powered directly from the output of many logic gates.
