LM45BIM3 Description

Short technical summary and product information.

The LM45BIM3 from Texas Instruments is a precision integrated-circuit temperature sensor with an analog voltage output. Its output voltage is linearly proportional to the Celsius temperature, simplifying interface to readout or control circuitry. The sensor provides an accuracy of ±2°C at room temperature and ±3°C over its full operating range of -20°C to 100°C.

 

Key electrical characteristics include a supply voltage range of 4V to 10V and a low supply current draw of less than 120 µA, resulting in very low self-heating (0.20°C in still air). The sensor features a linear scale factor of 10mV/°C and a nonlinearity of only ±0.8°C maximum over temperature. Its low output impedance is 20Ω for a 1 mA load.

 

Packaged in a SOT-23-3 surface-mount package, the LM45BIM3 is suitable for various applications requiring accurate local temperature monitoring. It operates directly in Celsius without requiring external calibration or trimming, thanks to wafer-level trimming and calibration.
