description/ordering information

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 previously was attained at the

expense of power consumption and trimming.

The LT1004C is characterized for operation from 0°C to 70°C. The LT1004I is characterized for operation from

−40°C to 85°C.
