-The LM34 series devices are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Fahrenheit temperature.
-The LM34 device has an advantage over linear temperature sensors calibrated in degrees Kelvin, because the user is not required to subtract a large constant voltage from its output to obtain convenient Fahrenheit scaling.
-The LM34 device does not require any external calibration or trimming to provide typical accuracies of ±1/2°F at room temperature and ±1-1⁄2°F over a full −50°F to 300°F temperature range.
-Lower cost is assured by trimming and calibration at the wafer level.
-The low output impedance, linear output, and precise inherent calibration of the LM34 device makes interfacing to readout or control circuitry especially easy.
-It can be used with single power supplies or with plus and minus supplies.
-Because the LM34 device draws only 75 µA from its supply, the device has very low self-heating, less than 0.2°F in still air.
-The LM34 device is rated to operate over a −50°F to 300°F temperature range, while the LM34C is rated for a −40°F to 230°F range (0°F with improved accuracy).
-The LM34 devices are series is available packaged in hermetic TO-46 transistor packages; while the LM34C, LM34CA, and LM34D are available in the plastic TO-92 transistor package.
-The LM34D device is available in an 8-lead, surface-mount, small-outline package.
-The LM34 device is a complement to the LM35 device (Centigrade) temperature sensor.
