PRODUCT HIGHLIGHTS
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 AD587L has a
maximum deviation from 10.000 V of
±
8.5 mV between 0
°
C
and +70
°
C, and the AD587U guarantees
±
14 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 10 volt refer-
ence can be upgraded instantly with the AD587.
4. Output noise of the AD587 is very low, typically 4
μ
V p-p. A
noise reduction pin is provided for additional noise filtering
using an external capacitor.
5. The AD587 is available in versions compliant with MIL-
STD-883. Refer to the Analog Devices Military Products
Databook or current AD587/883B data sheet for detailed
specifications.
PRODUCT DESCRIPTION
The AD587 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 AD587 provides outstanding perfor-
mance at low cost.
The AD587 offers much higher performance than most other
10 V references. Because the AD587 uses an industry standard
pinout, many systems can be upgraded instantly with the
AD587. The buried Zener approach to reference design pro-
vides lower noise and drift than bandgap voltage references. The
AD587 offers a noise reduction pin which can be used to further
reduce the noise level generated by the buried Zener.
The AD587 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 AD587J, K and L are specified for operation from 0
°
C to
+70
°
C, and the AD587S, T and U are specified for –55
°
C to
+125
°
C operation. All grades are available in 8-pin cerdip. The
J and K versions are also available in an 8-pin Small Outline IC
(SOIC) package for surface mount applications, while the J, K,
and L grades also come in an 8-pin plastic package.
