Texas Instruments LM45
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. The LM45's low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy.| Part No. | LM45 |

DESCRIPTION
Low cost is assured by trimming and calibration at the wafer level. It can be used with a single power supply, or with plus and minus supplies. As it draws only 120 μA from its supply, it has very low self-heating, less than 0.2°C in still air. The LM45 is rated to operate over a −20° to +100°C temperature range. Connection Diagram Figure 1.
