LM34

Precision Fahrenheit Temperature Sensors

Texas Instruments

The LM34 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Fahrenheit temperature.

Product Description

The LM34 thus has an advantage over linear temperature sensors calibrated in degrees Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Fahrenheit scaling. The LM34 does not require any external calibration or trimming to provide typical accuracies of ±1/2°F at room temperature and ±11/2°F over a full -50 to 300°F temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM34’s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies or with plus and minus supplies. As it draws only 75µA from its supply, it has very low self-heating, less than 0.2°F in still air.
