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 con-
stant voltage from its output to obtain convenient Fahrenheit
scaling. The LM34 does not require any external calibration
or trimming to provide typical accuracies of

temperature and

F over a full 50 to +300F tempera-
ture 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 75 μA from its supply, it has very low
self-heating, less than 0.2F in still air. The LM34 is rated to
operate over a 50 to +300F temperature range, while the
LM34C is rated for a 40 to +230F range (0F with im-
proved accuracy). The LM34 series is available packaged in
hermetic TO-46 transistor packages, while the LM34C,
LM34CA and LM34D are also available in the plastic TO-92
transistor package. The LM34D is also available in an 8-lead
surface mount small outline package. The LM34 is a comple-
ment to the LM35 (Centigrade) temperature sensor.
