LM20
2.4V, 10µA, SC70, micro SMD Temperature Sensor
General DescriptionThe LM20 is a precision analog output CMOS
integrated-circuit temperature sensor that operates overa
−55˚Cto +130˚C temperature range. The power supply op-
erating rangeis +2.4Vto +5.5V. The transfer functionof
LM20is predominately linear, yet hasa slight predictable
parabolic curvature. The accuracyofthe LM20 when speci-
fiedtoa parabolic transfer functionis ±1.5˚Catan ambient
temperatureof +30˚C. The temperature error increaseslin-
early and reachesa maximumof ±2.5˚Catthe temperature
range extremes. The temperature rangeis affectedby the
power supply voltage.Ata power supply voltageof2.7Vto
5.5V the temperature range extremes are +130˚C and
−55˚C. Decreasing the power supply voltageto 2.4V
changesthe negative extremeto −30˚C, while the positive
remainsat +130˚C.
The LM20’s quiescent currentis less than10 µA. Therefore,
self-heatingis less than 0.02˚Cin stillair. Shutdown capa-
bilityforthe LM20is intrinsic becauseits inherent low power
consumption allowsittobe powered directly fromthe output many logic gatesor doesnot necessitate shutdownatall.
