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.
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 tem-
perature coefficient, see the LT1034 data sheet.
