The AD589 is a 2-terminal, low cost, temperature compensated
band gap voltage reference that provides a fixed 1.23V output
voltage for input currents between 50
reference voltage for a wide range of input current.
2. Output impedance of 0.6 and temperature coefficients as
low as 10 ppm/°C ensure stable output voltage over a wide
range of operating conditions.
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 tech-
nology combine to provide excellent performance at low cost.
3. The AD589 can be operated as a positive or negative refer-
ence. Floating operation is also possible.
Additionally, the active circuit produces an output impedance 10
lower than the typical low-TC Zener diodes. This feature allows
operation with no external components required to maintain full
accuracy under changing load conditions.
4. The AD589 will operate with a total current as low as 50
(60 W total power dissipation), ideal for battery-powered
instrument applications.
5. The AD589 is an exact replacement for other 1.2V references,
offering superior temperature performance and reduced sensi-
tivity to capacitive loading.
The AD589 is available in seven versions. The AD589J, AD589K,
AD589L, and AD589M grades are specified for 0°C to +70°C
operation, while the AD589S and AD589T grades are rated for
the full –55°C to +125°C temperature range. All grades are avail-
able in a metal can (H-02) package. The AD589J is also available
in an 8-lead SOIC package.
6. The AD589 is available in versions compliant with MIL-
STD-883. Consult factory for 883 data sheet.

NOTES
1See theVoltageVariation versusTemperature section for explanation of temperature coefficient measurement method.
2Optimum performance is obtained at currents below 500 A. For current operation below 200 A, stray shunt capacitances should be limited to 20 pF or increased to
1 F. If strays cannot be avoided, operation at 500 A and a shunt capacitor of at least 1000 pF are recommended.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily accumulate
on the human body and test equipment and can discharge without detection.Although the AD589 features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
REV. C
Dynamic Performance
VoltageVariationVersusTemperature
Many low power instrument manufacturers are becoming increas-
ingly concerned with the turn-on characteristics of the components
being used in their systems. Fast turn-on components often enable
the end user to keep power off when not needed and yet respond
quickly when the power is turned on for operation. Figure 3 dis-
plays the turn-on characteristics of the AD589. This characteristic
is generated from cold-start operation and represents the true turn-
on waveform after an extended period with the supplies off. The
figure shows both the coarse and fine transient characteristics of
the device; the total settling time to within ±1 mV is about 25 s,
and there is no long thermal tail appearing after that point.
Some confusion exists in the area of defining and specifying
reference voltage error over temperature. Historically, references
have been characterized using a maximum deviation per degree
Centigrade, i.e., 10 ppm/°C. However, because of nonlinearities
in temperature characteristics, which originated in standard Zener
references (such as S type characteristics), most manufacturers
have begun to use a maximum limit error band approach to specify
devices. This technique involves measurement of the output at
3, 5, or more different temperatures to guarantee that the output
voltage will fall within the given error band. The temperature
characteristics of the AD589 consistently follows the curve shown
in Figure 1. Three-point measurement guarantees the error band
over the specified temperature range. The temperature coefficients
specified in the Specifications section represent the slopes of the

The AD589 functions as a 2-terminal shunt-type regulator. It
provides a constant 1.23 V output for a wide range of input
A to 5 mA. Figure 5 shows the simplest con-
figuration for an output voltage of 1.2 V or less. Note that no
frequency compensation is required. If additional filtering is
desired for ultralow noise applications, minimum recommended
capacitance is 1000 pF.

other values of reference voltage. Figure 6 shows a circuit that

DACs, such as the AD7533. These DACs require a negative
reference voltage in order to provide a positive output range.
