PRODUCT DESCRIPTION
PRODUCT HIGHLIGHTS
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 perfor-
mance 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 pro-
vides 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-pin plastic DIP. The AD586J, K, L, A and B are available in
an 8-pin plastic surface mount small outline (SO) package. The
AD586J, K, L, S and T are available in an 8-pin cerdip package.
1. Laser trimming of both initial accuracy and temperature
coefficients results in very low errors over temperature with-
out 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 fine-
trim 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 MIL-
STD-883. Refer to the Analog Devices Military Products
Databook or current AD586/883B data sheet for detailed
specifications.
