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, self-

heating is limited to a very low 0.2°C in still air.

Shutdown capability for the LM62 is intrinsic because

its inherent low power consumption allows it to be

powered directly from the output of many logic gates.
