The LM45BIM3 is a precision integrated-circuit Temperature Sensor, 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. As it draws only 120µA from its supply, it has very low self-heating, less than 0.2°C in still air.
