FM20 - Ultra-Low-Power Analog Temperature Sensor

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.

Features

  • Analog Output, -11.77mV/°C Range, -55 to 130°C Accuracy, ±1°C at 25°C Supply Current, 9µA typical Output Drive, 1µA Self-heating < 0.021°C Operating Voltage: +2.4V to +6V.

www.fairchildsemi.com FM20 Ultra-Low-Power Analog Temperature Sensor Features • • • • • • • Analog Output, -11.77mV/°C Range, -55 to 130°C Accuracy, ±1°C at 25°C Supply Current, 9µA typical Output Drive, 1µA Self-heating < 0.021°C Operating Voltage: +2.4V to +6V 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.
