LM94023 Datasheet Dual-Gain Analog Temperature Sensor

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The LM94023 is a precision analog output CMOS integratedcircuit temperature sensor that operates at a supply voltage as low as 1.5 Volts.

Available in the very small four-bump microSMD 0.8mm x 0.8mm) the LM94023 occupies very little board area.

A class-AB output structure gives the LM94023 strong output source and sink current capability for driving heavy loads, making it well suited to source the input of a sample-and-hold analog-to-digital converter with its transient load requirements, This generally means the LM94023 can be used without external components, like resistors and buffers, on the output.
