DescriptionThe 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 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 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 to +70, and the AD587S, T and U are specified for 55 to +125 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.
