LM50
SOT-23 Single-Supply Centigrade Temperature Sensor
General Description

The LM50isa precision integrated-circuit temperature sen-
sorthatcan sensea −40˚Cto +125˚Ctemperature rangeus-
inga single positive supply.The LM50’soutput voltageislin-
early proportionalto Celsius (Centigrade) temperature
(+10 mV/˚C)andhasaDC offsetof +500mV.The offsetal-
lows reading negative temperatures withoutthe needfora
negativesupply. Theideal output voltage ofthe LM50 ranges
from +100mVto +1.75Vfora −40˚Cto +125˚C temperature
range.The LM50 doesnot requireany externalcalibrationor
trimmingto provide accuraciesof ±3˚Cat roomtemperature
and ±4˚C overthefull −40˚Cto +125˚C temperature range.
Trimmingand calibrationofthe LM50atthe wafer levelas-
surelow costand high accuracy.The LM50’s linear output,
+500mV offset,and factory calibration simplify circuitryre-
quiredina single supply environment where reading nega-
tive temperaturesis required. Becausethe LM50’squiescent
currentisless than130μA, self-heatingis limitedtoa very
low 0.2˚Cinstillair.
Applications
Computers Disk Drives Battery Management Automotive FAX Machines Printers Portable Medical Instruments HVAC Power Supply Modules
