GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The AD587 represents a major advance in state-of-the-art
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
performance 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 provides lower
noise and drift than band gap voltage references. The AD587
offers a noise-reduction pin that 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-bit,
10-bit, 12-bit, 14-bit, or 16-bit DACs that require an external
precision reference. The device is also ideal for successive
approximation or integrating ADCs with up to 14 bits of
accuracy. In general, it offers better performance than standard
on-chip references.
The AD587J and AD587K are specified for operation from 0°C
to 70°C, and the AD587U is specified for operation from ?55°C
to +125°C. The AD587JQ and AD587UQ models are available
in 8-lead CERDIP. Other models are available in an 8-lead SOIC
package for surface-mount applications, or in an 8-lead PDIP.

Laser trimming of both initial accuracy and temperature
coefficients. This laser trimming results in very low errors
over temperature without the use of external components.
The AD587U guarantees ±14 mV maximum total error
between ?55°C and +125°C.
Optional fine trim connection. This connection is designed
for applications requiring higher precision.
Instant upgrade of any system using an industry-standard
pinout 10 V reference.
Very low output noise. AD587 output noise is typically
4 μV p-p. A noise-reduction pin is provided for additional
noise filtering using an external capacitor.
