PRODUCT DESCRIPTION
The AD586 represents a major advance in the state-of-the-art in
monolithic voltage references. Using a proprietary ion-implanted
buried Zener diode and laser wafer trimming of high stability
thin-film resistors, the AD586 provides outstanding performance at low cost.
The AD586 offers much higher performance than most other
5 V references. Because the AD586 uses an industry standard
pinout, many systems can be upgraded instantly with the AD586.
The buried Zener approach to reference design provides lower
noise and drift than bandgap voltage references. The AD586
offers a noise reduction pin which can be used to further reduce
the noise level generated by the buried Zener.
The AD586 is recommended for use as a reference for 8-, 10-,
12-, 14-, or 16-bit D/A converters which require an external
precision reference. The device is also ideal for successive
approximation or integrating A/D converters with up to 14 bits
of accuracy and, in general, can offer better performance than
the standard on-chip references.
The AD586J, K, L, and M are specified for operation from 0°C
to 70°C, the AD586A and B are specified for –40°C to +85°C
operation, and the AD586S and T are specified for –55°C to
+125°C operation. The AD586J, K, L, and M are available in
an 8-lead plastic DIP. The AD586J, K, L, A, and B are available in an 8-lead plastic surface mount small outline (SO)
package. The AD586J, K, L, S, and T are available in an 8-lead
cerdip package.

PRODUCT HIGHLIGHTS
1. Laser trimming of both initial accuracy and temperature
coefficients results in very low errors over temperature without the use of external components. The AD586M has a
maximum deviation from 5.000 V of ±2.45 mV between
0°C and 70°C, and the AD586T guarantees ±7.5 mV maximum total error between –55°C and +125°C.
2. For applications requiring higher precision, an optional finetrim connection is provided.
3. Any system using an industry standard pinout reference can
be upgraded instantly with the AD586.
4. Output noise of the AD586 is very low, typically 4 µV p-p. A
noise reduction pin is provided for additional noise filtering
using an external capacitor.
5. The AD586 is available in versions compliant with MILSTD-883. Refer to the Analog Devices Military Products
Databook or current AD586/883B data sheet for detailed

Die Dimensions: The dimensions given have a tolerance of ± 2 mils.
Backing: The standard backside surface is silicon (not plated). Analog Devices does not
recommend gold-backed dice for most applications.
Edges: A diamond saw is used to separate wafers into dice thus providing perpendicular
edges halfway through the die.
In contrast to scribed dice, this technique provides a more uniform die shape and size. The
perpendicular edges facilitate handling (such as tweezer pick-up) while the uniform shape
and size simplifies substrate design and die attach.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD586 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.

AD586
THEORY OF OPERATION
The AD586 consists of a proprietary buried Zener diode reference, an amplifier to buffer the output and several high stability
thin-film resistors as shown in the block diagram in Figure 1.
This design results in a high precision monolithic 5 V output
reference with initial offset of 2.0 mV or less. The temperature
compensation circuitry provides the device with a temperature
coefficient of under 2 ppm/°C.
Using the bias compensation resistor between the Zener output
and the noninverting input to the amplifier, a capacitor can be
added at the NOISE REDUCTION pin (Pin 8) to form a lowpass filter and reduce the noise contribution of the Zener to
the circuit.

Figure 1. Functional Block Diagram
NOISE PERFORMANCE AND REDUCTION
The noise generated by the AD586 is typically less than 4 µV p-p
over the 0.1 Hz to 10 Hz band. Noise in a 1 MHz bandwidth is
approximately 200 µV p-p. The dominant source of this noise is
the buried Zener which contributes approximately 100 nV/√Hz. In
comparison, the op amp’s contribution is negligible. Figure 3
shows the 0.1 Hz to 10 Hz noise of a typical AD586. The noise
measurement is made with a bandpass filter made of a 1-pole
high-pass filter with a corner frequency at 0.1 Hz and a 2-pole
low-pass filter with a corner frequency at 12.6 Hz to create a
filter with a 9.922 Hz bandwidth.
If further noise reduction is desired, an external capacitor may
be added between the NOISE REDUCTION pin and ground as
shown in Figure 2. This capacitor, combined with the 4 kΩ R
S
and the Zener resistances form a low-pass filter on the output of
the Zener cell. A 1 µF capacitor will have a 3 dB point at 12 Hz,
and it will reduce the high frequency (to 1 MHz) noise to about
160 µV p-p. Figure 4 shows the 1 MHz noise of a typical AD586
both with and without a 1 µF capacitor.
APPLYING THE AD586
The AD586 is simple to use in virtually all precision reference applications. When power is applied to Pin 2 and Pin 4
is grounded, Pin 6 provides a 5 V output. No external components are required; the degree of desired absolute accuracy is
achieved simply by selecting the required device grade. The
AD586 requires less than 3 mA quiescent current from an
operating supply of 12 V or 15 V.
An external fine trim may be desired to set the output level to
exactly 5.000 V (calibrated to a main system reference). System
calibration may also require a reference voltage that is slightly
different from 5.000 V, for example, 5.12 V for binary applications. In either case, the optional trim circuit shown in Figure 2
can offset the output by as much as 300 mV, if desired, with
minimal effect on other device characteristics.

TURN-ON TIME
Upon application of power (cold start), the time required for the
output voltage to reach its final value within a specified error
band is defined as the turn-on settling time. Two components
normally associated with this are: the time for the active circuits
to settle, and the time for the thermal gradients on the chip to
stabilize. Figure 5 shows the turn-on characteristics of the
AD586. It shows the settling to be about 60 µs to 0.01%. Note
the absence of any thermal tails when the horizontal scale is
expanded to l ms/cm in Figure 5b.
Output turn-on time is modified when an external noise reduction capacitor is used. When present, this capacitor acts as an
additional load to the internal Zener diode’s current source,
resulting in a somewhat longer turn-on time. In the case of a
1 µF capacitor, the initial turn-on time is approximately 400 ms
to 0.01% (see Figure 5c).
DYNAMIC PERFORMANCE
The output buffer amplifier is designed to provide the AD586
with static and dynamic load regulation superior to less complete references.
Many A/D and D/A converters present transient current loads
to the reference, and poor reference response can degrade the
converter’s performance.

Centigrade; i.e., 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 the measurement of the
output at three or more different temperatures to specify an
output voltage error band.
Figure 9 shows the typical output voltage drift for the AD586L

The AD586 is designed for precision reference applications

Each AD586J, K and L grade unit is tested at 0°C, 25°C, and
70°C. Each AD586SQ and TQ grade unit is tested at –55°C,
+25°C, and +125°C. This approach ensures that the variations
of output voltage that occur as the temperature changes within
the specified range will be contained within a box whose diagonal has a slope equal to the maximum specified drift. The
position of the box on the vertical scale will change from device
to device as initial error and the shape of the curve vary. The
maximum height of the box for the appropriate temperature
range and device grade is shown in Table I. Duplication of these
results requires a combination of high accuracy and stable temperature control in a test system. Evaluation of the AD586 will
produce a curve similar to that in Figure 9, but output readings
may vary depending on the test methods and equipment utilized.

USING THE AD586 WITH CONVERTERS
The AD586 is an ideal reference for a wide variety of 8-, 12-,
14-, and 16-bit A/D and D/A converters. Several representative
examples follow.
5 V REFERENCE WITH MULTIPLYING CMOS D/A OR A/D CONVERTERS
The AD586 is ideal for applications with 10- and 12-bit multiplying CMOS D/A converters. In the standard hookup, as
shown in Figure 11, the AD586 is paired with the AD7545
12-bit multiplying DAC and the AD711 high-speed BiFET Op
Amp. The amplifier DAC configuration produces a unipolar
0 V to –5 V output range. Bipolar output applications and
other operating details can be found on the individual product data sheets.
The AD586 can also be used as a precision reference for multiple DACs. Figure 12 shows the AD586, the AD7628 dual
DAC and the AD712 dual op amp hooked up for single supply
operation to produce 0 V to –5 V outputs. Because both DACs
are on the same die and share a common reference and output
op amps, the DAC outputs will exhibit similar gain TCs.

STACKED PRECISION REFERENCES FOR MULTIPLE VOLTAGES
Often, a design requires several reference voltages. Three
AD586s can be stacked, as shown in Figure 13, to produce
5.000 V, 10.000 V, and 15.000 V outputs. This scheme can be
extended to any number of AD586s as long as the maximum
load current is not exceeded. This design provides the additional advantage of improved line regulation on the 5.0 V
output. Changes in V
of 18 V to 50 V produces an output
IN
change that is below the noise level of the references.

you can vary the load current from the quiescent current (2 mA
typically) to approximately 10 mA. The compliance voltage of
