The LM60 device is a precision integrated-circuit temperature sensor that
can sense a −40°C to +125°C temperature range while operating from a single 2.7-V supply. The
output voltage of the device is linearly proportional to Celsius (Centigrade) temperature (6.25
mV/°C) and has a DC offset of
424 mV. The offset allows reading negative temperatures without the need for a negative
supply. The nominal output voltage of the device ranges from 174 mV to 1205 mV for a −40°C to
+125°C temperature range. The device is calibrated to provide accuracies of ±2°C at room
temperature and ±3°C over the full −25°C to +125°C temperature range. The linear output of the device, 424-mV offset, and factory calibration simplify external
circuitry required in a single supply environment where reading negative temperatures is required.
Because the quiescent current of the device is less than 110 µA, self-heating is limited to a very
low 0.1°C in still air in the SOT-23 package. Shutdown capability for the device is intrinsic
because its inherent low power consumption allows it to be powered directly from the output of many
logic gates.
