LM60  Product Folder

The LM60 is a precision integrated-circuit temperature sensor that can sense a -40°C to +125°C temperature range while operating from a single +2.7V supply. The LM60's output voltage 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 LM60 ranges from +174 mV to +1205 mV for a -40°C to +125°C temperature range. The LM60 is calibrated to provide accuracies of ±2.0°C at room temperature and ±3°C over the full -25°C to +125°C temperature range.

The LM60's linear output, +424 mV offset, and factory calibration simplify external circuitry required in a single supply environment where reading negative temperatures is required. Because the LM60's quiescent current 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 LM60 is intrinsic because its inherent low power consumption allows it to be powered directly from the output of many logic gates.
