6 mV/˚C, SOT-23 Temperature Sensor June 1999 LM62 2.
7V, 15.
6 mV/˚C SOT-23 Temperature Sensor General Description 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.
The nominal output voltage of the LM62 ranges from +480 mV to +1884 mV for a 0˚C to +90˚C temperature range.
The LM62 is calibrated to provide accuracies of ± 2.
0˚C at room temperature and +2.
5˚C/ −2.
0˚C over the full 0˚C to +90˚C temperature range.
The LM62’s linear output, +480 mV offset, and factory calibration simplify external circuitry required in a single supply environment where reading temperatures down to 0˚C is required.
Because the LM62’s quiescent current is less than 130 µA,...
