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
specifications.

ESD SENSITIVE DEVICE
AD586
The following specifications are tested at the dice level for AD586JCHIPS. These die are probed at 25ⴗC
only. (TA = 25ⴗC, VIN = 15 V unless otherwise noted.)
Die Thickness: The standard thickness of Analog Devices Bipolar dice is 24 mils ± 2 mils.
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.
Top Surface: The standard top surface of the die is covered by a layer of glassivation. All
areas are covered except bonding pads and scribe lines.
Surface Metalization: The metalization to Analog Devices bipolar dice is aluminum.
Minimum thickness is 10,000Å.
Bonding Pads: All bonding pads have a minimum size of 4 mils by 4 mils. The passivation
windows have 3.5 mils by 3.5 mils minimum.
pads should be connected to the output.

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.
