LM20EP

Enhanced Plastic 2.4V, 10µA, SC70, micro SMD

Temperature Sensor

General Description

Features

n Rated for full −55˚C to +130˚C range

The LM20EP is a precision analog output CMOS integrated-

circuit temperature sensor that operates over a −55˚C to

+130˚C temperature range. The power supply operating

range is +2.4 V to +5.5 V. The transfer function of LM20EP is

predominately linear, yet has a slight predictable parabolic

curvature. The accuracy of the LM20EP when specified to a

parabolic transfer function is 1.5˚C at an ambient tempera-

ture of +30˚C. The temperature error increases linearly and

reaches a maximum of 2.5˚C at the temperature range

extremes. The temperature range is affected by the power

supply voltage. At a power supply voltage of 2.7 V to 5.5 V

the temperature range extremes are +130˚C and −55˚C.

Decreasing the power supply voltage to 2.4 V changes the

negative extreme to −30˚C, while the positive remains at

+130˚C.

The LM20EP’s quiescent current is less than 10 µA. There-

fore, self-heating is less than 0.02˚C in still air. Shutdown

capability for the LM20EP is intrinsic because its inherent

low power consumption allows it to be powered directly from

the output of many logic gates or does not necessitate

shutdown at all.
