description
The LT1004 micropower voltage reference is a
two-terminal band-gap reference diode designed
to provide high accuracy and excellent
temperature characteristics at very low operating
currents. Optimizing the key parameters in the
design, processing, and testing of the device
results in specifications previously attainable only
with selected units.
The LT1004 is a pin-for-pin replacement for the LM285 and LM385 series of references, with improved
specifications. It is an excellent device for use in systems in which accuracy was previously attained at the
expense of power consumption and trimming.
The LT1004C is characterized for operation from 0

For ordering purposes, the decimal point in the part number must be replaced with a hyphen
(e.g., show the -1.2 suffix as -1-2 and the -2.5 suffix as -2-5). The D package is available taped
and reeled. Add the R suffix to the device type (e.g., LT1004CDR-1-2). The PW package is only
available taped and reeled
