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.
