TMP37GRTZ-REEL7

TMP37GRTZ-REEL7 is a low voltage temperature sensor. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature. The low output impedance of the sensor and its linear output and precise calibration simplify interfacing to temperature control circuitry and ADCs. The supply current runs well below 50µA, providing very low self-heating—less than 0.1°C in still air. In addition, a shutdown function is provided to cut the supply current to less than 0.5µA. The sensor is functionally compatible with the LM35/LM45 and provides a 250mV output at 25°C. This temperature sensor is widely used in application such as environmental control systems, thermal protection, industrial process control, fire alarms, power system monitors, CPU thermal management etc.
