com FM50 Analog Temperature Sensor Features • • • • • • • Analog output: 10 mV/°C Range: -40 to 125°C range: Accuracy: ±1°C at 25°C Supply Current, 170 µA max.
Output Drive, 25 µA Self-heating < 0.
1°C Operating Voltage: +2.
4V to +6V Description As a precision CMOS temperature sensor, the FM50 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 130µA.
For normal operation, the load on VOUT should be 100KΩ or less.
In a typical application, a remotely mounted FM50 is monitored by a microcontroller with an analog A/D converter input.
Alternatively, the FM50 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.
Package is a 3-pin SOT-23 Applications • • • • • • • • Mobile Phones Computers Battery Management Office Equipment HVAC Power Supply Modules Disk Drive...
