LM19 2.4V, 10µA, TO-92 Temperature Sensor

Check for Samples: LM19

FEATURES

DESCRIPTION

The LM19 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 LM19 is predominately linear,

yet has a slight predictable parabolic curvature. The

accuracy of the LM19 when specified to a parabolic

transfer function is ±2.5°C at an ambient temperature

of +30°C. The temperature error increases linearly

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 LM19's quiescent current is less than 10 μA.

Therefore, self-heating is less than 0.02°C in still air.

Shutdown capability for the LM19 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.
