DESCRIPTIO
The LT
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 attain-
able 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
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.
For a low drift micropower reference with guaranteed
temperature coefficient, see the LT1034 data sheet.
