As a precision CMOS temperature sensor, the FM20 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 1µA. For normal operation, the load on V_OUT should be 5MW or less.

In a typical application, a remotely mounted FM20 is monitored by a microcontroller with an analog A/D converter input. Alternatively, the FM20 can drive a comparator with a high impedance input.

Accuracy is typically ±1°C at room temperature; and better than ±2.5°C from 0 to 50°C.

Available packages are surface mount 5-pin SC70 and 3-pin SOT-23.
