General DescriptionThe LM34series areprecision integrated-circuittemperature
sensors, whose output voltageis linearly proportionaltothe
Fahrenheit temperature. The LM34 thushasan advantage
over linear temperature sensors calibratedin degrees
Kelvin,asthe userisnot requiredto subtracta large con-
stantvoltage fromits outputto obtain convenient Fahrenheit
scaling.The LM34 doesnot requireany external calibration trimmingto provide typical accuraciesof ±1⁄2˚Fat room
temperatureand ±11⁄2˚F overafull−50to +300˚F tempera-
ture range. Low costis assuredby trimmingand calibrationthe wafer level.The LM34’slow output impedance, linear
output,and precise inherent calibration make interfacingto
readoutor control circuitry especially easy.Itcanbe used
with single power suppliesor with plusand minus supplies.it draws only75μA fromits supply,it has verylow
self-heating, less than 0.2˚Finstillair.The LM34is ratedto
operate overa −50˚to +300˚F temperature range, whilethe
LM34Cis ratedfora −40˚to +230˚F range (0˚F withim-
proved accuracy).The LM34 seriesis available packagedin
hermetic TO-46 transistor packages, whilethe LM34C,
LM34CAand LM34Dare also availableinthe plastic TO-92
transistorpackage. TheLM34D isalso availableinan 8-lead
surface mount small outline package. TheLM34isa comple-
menttothe LM35 (Centigrade) temperature sensor.
Features Calibrated directlyin degrees Fahrenheit Linear +10.0 mV/˚F scale factor 1.0˚F accuracy guaranteed(at +77˚F) Ratedforfull −50˚to +300˚F range Suitablefor remote applications Low costdueto wafer-level trimming Operates from5to30 volts Less than90μA current drain Low self-heating, 0.18˚Finstillair Nonlinearity only ±0.5˚F typical Low-impedance output, 0.4Ωfor1 mAload
