LT1004

Micropower Voltage

Reference

FEATURES

DESCRIPTION

The LT^®1004 Micropower Voltage Reference is a

2-terminal bandgap reference diode designed to provide

highaccuracyandexcellenttemperaturecharacteristicsat

very low operating currents. Optimization of the key

parameters in the design, processing and testing of the

deviceresultsinaccuracyspecificationspreviouslyattain-

ableonlywithselectedunits. Belowisadistributionplotof

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

all of the units fall well within the prescribed limits of

±4mV.

■

Guaranteed ±4mV Initial Accuracy LT1004-1.2

■

Guaranteed ±20mV Accuracy LT1004-2.5

■

Guaranteed 10µA Operating Current

■

Guaranteed Temperature Performance

■

Operates up to 20mA

■

Very Low Dynamic Impedance

APPLICATIONS

■

Portable Meter References

■

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.

Battery-Operated Systems

Current Loop Instrumentation

■

For a low drift micropower reference with guaranteed

temperature coefficient, see the LT1034 data sheet.
