REF1004
1.2V and 2.5V Micropower
VOLTAGE REFERENCE
FEATURES
DESCRIPTION
● INITIAL ACCURACY:
REF1004-1.2 ±4mV
REF1004-2.5 ±20mV
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.
● MINIMUM OPERATING CURRENT:
REF1004-1.2 10µA
REF1004-2.5 20µA
● EXCELLENT LONG TERM
TEMPERATURE STABILITY
● VERY LOW DYNAMIC IMPEDANCE
● OPERATES UP TO 20mA
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.
● PACKAGE: 8-Lead SOIC
APPLICATIONS
● BATTERY POWERED TEST EQUIPMENT
● PORTABLE MEDICAL INSTRUMENTATION
● PORTABLE COMMUNICATIONS DEVICES
● A/D AND D/A CONVERTERS
The REF1004 is offered in an 8-lead Plastic SOIC
package and shipped in anti-static rails or tape and
reel.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder
temperature.
