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.
