LM60 2.7V, SOT-23 or TO-92 Temperature Sensor July 2001 LM60 2.7V, SOT-23 or TO-92 Temperature Sensor General Description 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. n Available in SOT-23 and TO-92 packages Applications n n n n n n n n n Cellular Phones Computers Power Supply Modules Battery Management FAX Machines Printers HVAC Disk Drives Appliances Key Specifications n n n n n n n n Features n Calibrated linear scale factor of ...
