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.

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 µV 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
