LM45 SOT-23 Precision Centigrade Temperature Sensors July 1999 LM45 SOT-23 Precision Centigrade Temperature Sensors General Description The LM45 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM45 does not require any external calibration or trimming to provide accuracies of ± 2˚C at room temperature and ± 3˚C over a full −20 to +100˚C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM45’s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with a single power supply, or with plus and minus supplies.
