GENERAL DESCRIPTION

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.

PRODUCT HIGHLIGHTS

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.

MIL-STD-883-compliant versions available. Refer to the

Analog Devices Military/Aerospace Reference Manual for

detailed specifications.
