Low-Voltage Negative Slope Analog Temp Sensor for LM20 applications

|
General 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 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.
