The FT1004 micropower voltage reference is a
2-terminal bandgap reference diode designed to provide
high accuracy and excellent temperature characteristics at
very low operating currents. Optimisation 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 FT1004-1.2. Virtually
all of the units fall well within the prescribed limits of
±4mV.
The FT1004 is a pin-for-pin replacement for the
FT185/385 series of references with improved accu-
racy specifications. More important, the FT1004 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 FT1034 data sheet.
