As a precision CMOS temperature sensor, the FM50 is cost effective for accurate, low-power, temperature-monitoring applications. Output voltage versus temperature is extremely linear. With no load, the supply current is typically 130µA. For normal operation, the load on V_OUT should be 100KW or less.

In a typical application, a remotely mounted FM50 is monitored by a microcontroller with an analog A/D converter input. Alternatively, the FM50 can drive a comparator with a high-impedance input.

Accuracy is typically ±0.5°C at room temperature, and better than ±2°C from 0 to 75°C.

FM50 is available in a 3-pin SOT-23 package.
