PRODUCT DESCRIPTION
The AD589 is a two-terminal, low cost, temperature compen-
sated bandgap voltage reference which provides a fixed 1.23 V
output voltage for input currents between 50 µA and 5.0 mA.
The high stability of the AD589 is primarily dependent upon
the matching and thermal tracking of the on-chip components.
Analog Devices’ precision bipolar processing and thin-film
technology combine to provide excellent performance at low
cost.
Additionally, the active circuit produces an output impedance
ten times lower than typical low-TC Zener diodes. This feature
allows operation with no external components required to
maintain full accuracy under changing load conditions.
The AD589 is available in seven versions. The AD589J, K, L
and M grades are specified for 0°C to +70°C operation, while
the S, T, and U grades are rated for the full –55°C to +125°C
temperature range. All grades are available in a metal can
(H-02A) package. The AD589J is also available in an 8-pin
SOIC package.
PRODUCT HIGHLIGHTS
1. The AD589 is a two-terminal device which delivers a
constant reference voltage for a wide range of input
current.
2. Output impedance of 0.6 Ω and temperature coefficients as
low as 10 ppm/°C insure stable output voltage over a wide
range of operating conditions.
3. The AD589 can be operated as a positive or negative
reference. “Floating” operation is also possible.
4. The AD589 will operate with total current as low as 50 µA
(60 µW total power dissipation), ideal for battery powered
instrument applications.
5. The AD589 is an exact replacement for other 1.2 V ref-
erences, offering superior temperature performance and
reduced sensitivity to capacitive loading.
6. The AD589 is available in versions compliant with MIL-
STD-883. Refer to the Analog Devices Military Products
Databook or current AD589/883B data sheet for detailed
specifications.
