Precision Centigrade Temperature Sensors
General DescriptionThe LM35 seriesare precision integrated-circuit temperature
sensors, whose output voltageis linearly proportionalto the
Celsius (Centigrade) temperature. The LM35 thus hasan
advantage over linear temperature sensors calibratedin Kelvin,as the useris not requiredto subtracta large
constant voltage fromits outputto obtain convenient Centi-
grade scaling. The LM35 does not require any external
calibrationor trimmingto provide typical accuraciesof ±1⁄4˚C room temperature and ±3⁄4˚C overa full −55to +150˚C
temperature range. Low costis assuredby trimming and
calibrationatthe wafer level. The LM35’s low output imped-
ance, linear output, and precise inherent calibration make
interfacingto readoutor control circuitry especially easy.It
canbe used with single power supplies,or with plus and
minus supplies.Asit draws only60 μAfromits supply,it has
very low self-heating, less than 0.1˚Cin stillair. The LM35is
ratedto operate overa −55˚to +150˚C temperature range,
while the LM35Cis ratedfora −40˚to +110˚C range (−10˚
with improved accuracy). The LM35 seriesis available pack-
agedin hermetic TO-46 transistor packages, while the
LM35C, LM35CA, and LM35D are also availablein the
plastic TO-92 transistor package. The LM35Dis also avail-
ableinan 8-lead surface mount small outline package anda
plastic TO-220 package.
