LM45B/LM45C SOT-23 Precision Centigrade Temperature Sensors. This sensor 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.
The LM45 series are integrated-circuit temperature sensors with an output voltage linearly proportional to Celsius temperature. They require no external calibration or trimming to provide accuracies of +2°C at room temperature and +3°C over a full -20 to +100°C range. The devices operate from a single power supply between 4.0V and 10V.
