FM20 - Fairchild Semiconductor

FM20 Ultra-Low-Power Analog Temperature Sensor

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 VOUT should be 5MΩ or less. In a typical application, a remotely mounted FM20 is monitored by.
