Overview
The AD587KRZ-REEL7, produced by Analog Devices Inc., is a high-precision 10 V voltage reference device. It represents a significant advancement in monolithic voltage references, utilizing a proprietary ion-implanted buried Zener diode and laser wafer trimming of high stability thin-film resistors. This design ensures outstanding performance at a low cost, offering higher precision than most other 10 V references. The device is compatible with industry-standard pinouts, making it easy to upgrade existing systems. The buried Zener approach provides lower noise and drift compared to band gap voltage references, and it includes a noise-reduction pin to further minimize noise levels.
