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.
