Low-Voltage Positive Slope with Offset Analog Temp Sensor for LM50 applications
| | | | | |

|
General 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 100KW 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.
FM50 is available in a 3-pin SOT-23 package.
