DESCRIPTION

The REF1004-1.2 and REF1004-2.5 are two terminal

bandgap reference diodes designed for high accuracy

with outstanding temperature characteristics at low

operating currents. Prior to the introduction of the

REF1004 Micropower Voltage References, accuracy

and stability specifications could only be attained by

expensive screening of standard devices. The REF1004

is a cost effective solution when reference voltage

accuracy, low power, and long term temperature sta-

bility are required.

REF1004 is a drop-in replacement for the LT1004 as

well as an upgraded replacement of the LM185/385

series references. The REF1004C is characterized for

operation from 0

°C to 70°C and the REF1004I is

characterized for operation from –40

°C to +85°C.

The REF1004 is offered in an 8-lead Plastic SOIC

package and shipped in anti-static rails or tape and

reel.
