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 and, in general, can offer better performance than the

standard on-chip references.

The AD587J, AD587K, and AD587L are specified for operation

from 0°C to 70°C, and the AD587U is specified for −55°C to

+125°C operation. All grades are available in 8-lead CERDIP.

The J and K versions are also available in an 8-lead SOIC

package for surface-mount applications, while the J, K, and L

grades also come 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

AD587L has a maximum deviation from 10.000 V of

±8.5 mV between 0°C and 70°C, and the AD587U guaran-

tees ±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 Products Databook

or the current AD587/883B Data Sheet for detailed

specifications.
