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 VOUT
should be 5MΩ 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.
