LM62 Overview
The LM62 is a precision integrated-circuit temperature sensor that can sense a 0˚C to +90˚C temperature range while operating from a single +3.0V supply. The LM62’s output voltage is linearly proportional to Celsius (Centigrade) temperature (+15.6 mV/˚C) and has a DC offset of +480 mV. The offset allows reading temperatures down to 0˚C without the need for a negative supply.
