SNIS161D – MARCH 2000 – REVISED JANUARY 2016 LM34 Precision Fahrenheit Temperature Sensors
1 Features 3 Description The LM34 series devices are precision integratedcircuit 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 В±1/2В°F at room temperature and
В±1-1вЃ„2В°F over a full -50В°F to 300В°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 …
