General Description
The LM45 seriesare precision integrated-circuit tempera-
ture sensors, whose outputvoltageis linearlyproportionalto
the Celsius (Centigrade) temperature. The LM45 doesnot
requireany external calibrationor trimmingto provide accu-
raciesof g2§Cat room temperatureand g3§C overafull
b20to a100§C temperature range. Low costis assuredby
trimmingand calibrationatthe wafer level.The LM45’slow
output impedance, linear output, and precise inherent cali-
bration make interfacingto readoutor control circuitry espe-
ciallyeasy. Itcanbe usedwitha singlepowersupply,orwith
plusand minus supplies.Asit draws only 120mA fromits
supply,ithas verylow self-heating, less than 0.2§Cinstill
air.The LM45is ratedto operate overa b20§to a100§C
temperature range.
