2.7V, SOT-23 Or TO-92 Temperature Sensor

The LM60 is a precision integrated-circuit Temperature Sensor that CAN sense a -40C to +125C 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 -40C to +125C temperature range. The LM60 is calibrated to provide accuracies of 2.0C at room temperature and 3C over the full -25C to +125C 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 ?A, self-heating is limited to a very low 0.1C 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
