LM62
2.7V, 15.6 mV/C SOT-23 Temperature Sensor
General Description
The LM62 is a precision integrated-circuit temperature sen-
sor that can sense a 0C to +90C temperature range while
operating from a single +3.0V supply. The LM62’s output
voltage is linearly proportional to Celsius (Centigrade) tem-
perature (+15.6 mV/C) and has a DC offset of +480 mV.
The offset allows reading temperatures down to 0C without
the need for a negative supply. The nominal output voltage of
the LM62 ranges from +480 mV to +1884 mV for a 0C to
+90C temperature range. The LM62 is calibrated to provide
accuracies of
±
2.0C at room temperature and +2.5C/
2.0C over the full 0C to +90C temperature range.
The LM62’s linear output, +480 mV offset, and factory cali-
bration simplify external circuitry required in a single supply
environment where reading temperatures down to 0C is
required. Because the LM62’s quiescent current is less than
130 μA, self-heating is limited to a very low 0.2C 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.
