Part Details:

LM62 August 2005 2.7V LM62 ,15.6 2.7V, 15.6 mV/°C SOT-23 Temperature SensorGeneral Description Features mV/°C, The LM62 is a precision integrated-circuit temperature sen- n Calibrated linear scale factor of +15.6 mV/°C sor that can sense a 0°C to +90°C temperature range while n Rated for full 0°C to +90°C range with 3.0V supply operating from a single +3.0V supply. The LM62 s output n Suitable for remote applications voltage is linearly proportional to Celsius (Centigrade) tem-perature (+15.6 mV/°C) and has a DC offset of +480 mV. Applications SOT The offset allows reading temperatures down to 0°C withoutthe need for a negative supply. The nominal output voltage of n Cellular Phones the LM62 ranges from +480 mV to +1884 mV for a 0°C to n Computers -23 +90°C temperature range. The LM62 is calibrated to provide n Power Supply Modules accuracies of ±2.0°C at room temperature and +2.5°C/ n Battery Management T -2.0°C over the full 0°C to +90°C temperature range. n FAX Machines emperature The LM62 s linear output, +480 mV offset, and factory cali- n Printers bration simplify external circuitry required in a single supply n HVAC environment where reading temperatures down to 0°C is n Disk Drives required. Because the LM62 s quiescent current is less than n Appliances 130 µA, self-heating is limited to a very low 0.2°C in still air.Shutdown capability for the LM62 is intrinsic because its Key Specifications inherent low power consumption allows it to be powereddirectly from the output of many logic gates. n Accuracy at 25°C ±2.0 or ±3.0°C (max) Sensor n Temperature Slope +15.6 mV/°C n Power Supply Voltage Range +2.7V to +10V n Current Drain @ 25°C 130 µA (max) n Nonlinearity ±0.8°C (max) n Output Impedance 4.7 k (max) Connection Diagram
