LM19
2.4V, 10µA, TO-92 Temperature Sensor
General DescriptionThe LM19isa precision analog output CMOS integrated-
circuit temperature sensor that operates overa −55˚Cto
+130˚C temperature range. The power supply operating
rangeis +2.4Vto +5.5V. The transfer functionof LM19is
predominately linear, yet hasa slight predictable parabolic
curvature. The accuracyof the LM19 when specifiedtoa
parabolic transfer functionis ±2.5˚Catan ambient tempera-
tureof +30˚C. The temperature error increases linearly and
reachesa maximumof ±3.8˚Cat the temperature range
extremes. The temperature rangeis affectedby the power
supply voltage.Ata power supply voltageof2.7Vto5.5V
the temperature range extremes are +130˚C and −55˚C.
Decreasing the power supply voltageto 2.4V changes the
negative extremeto −30˚C, while the positive remainsat
+130˚C.
The LM19’s quiescent currentis less than10 µA. Therefore,
self-heatingis less than 0.02˚Cin stillair. Shutdown capa-
bilityforthe LM19is intrinsic becauseits inherent low power
consumption allowsittobe powered directly fromthe output many logic gatesor doesnot necessitate shutdownatall.
