As a precision CMOS temperature sensor supplier, 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 5MOhm
or less.
In a typical application, a remotely mounted FM20 is monitored by a microcontroller with an analog A/D professional converter input. Alternatively, the FM20 can drive a comparator with a high impedance input.
