Part Details:

LM60 August 2005 2.7V LM60 ,SOT 2.7V, SOT-23 or TO-92 Temperature SensorGeneral Description n Available in SOT-23 and TO-92 packages -23 The LM60 is a precision integrated-circuit temperature sen- Applications sor that can sense a -40°C to +125°C temperature range or while operating from a single +2.7V supply. The LM60 s n Cellular Phones output voltage is linearly proportional to Celsius (Centigrade) n Computers T temperature (+6.25 mV/°C) and has a DC offset of +424 mV. O-92 n Power Supply Modules The offset allows reading negative temperatures without the n Battery Management need for a negative supply. The nominal output voltage of the n FAX Machines LM60 ranges from +174 mV to +1205 mV for a -40°C to n Printers T +125°C temperature range. The LM60 is calibrated to pro- emperature n HVAC vide accuracies of ±2.0°C at room temperature and ±3°Cover the full -25°C to +125°C temperature range. n Disk Drives n Appliances The LM60 s linear output, +424 mV offset, and factory cali-bration simplify external circuitry required in a single supplyenvironment where reading negative temperatures is re- Key Specifications quired. Because the LM60 s quiescent current is less than n Accuracy at 25°C: ±2.0 and ±3.0°C (max) 110 µA, self-heating is limited to a very low 0.1°C in still air in n Accuracy for -40°C to +125°C: ±4.0°C (max) the SOT-23 package. Shutdown capability for the LM60 is n Accuracy for -25°C to +125°C: ±3.0°C (max) Sensor intrinsic because its inherent low power consumption allows n Temperature Slope: +6.25mV/°C it to be powered directly from the output of many logic gates. n Power Supply Voltage Range: +2.7V to +10V Features n Current Drain @ 25°C: 110µA (max) n Nonlinearity:
