DescripTion

The LT^®1004 micropower voltage reference is a

2-terminal bandgap reference diode designed to provide

high accuracy and excellent temperature characteristics

at very low operating currents. Optimization of the key

parameters in the design, processing and testing of

the device results in accuracy specifications previously

attainable only with selected units. Below is a distribution

plot of reference voltage for a typical lot of LT1004-1.2.

Virtually all of the units fall well within the prescribed

limits of 4mV.

Portable Test Instruments

The LT1004 is a pin-for-pin replacement for the

LM185/LM385 series of references with improved accu-

racy specifications. More important, the LT1004 is an

attractive device for use in systems where accuracy was

previously obtained at the expense of power consump-

tion and trimming.
