LM45 Datasheet (National Semiconductor) - SOT-23 Precision Centigrade Temperature Sensors

LM45, SOT-23 Precision Centigrade Temperature Sensors

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
