PCB CMOS temperature sensor Fairchild Semiconductor

Description:

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 5MOhm
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 ±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.
