LM34 Precision Fahrenheit Temperature Sensors July 1999 LM34 Precision Fahrenheit Temperature Sensors General Description The LM34 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Fahrenheit temperature. 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...
