Product Introduction

Overview

The AD587KR, produced by Analog Devices Inc., represents a significant advancement in the field of monolithic voltage references. This device utilizes a proprietary ion-implanted buried Zener diode and laser wafer trimming of high stability thin-film resistors, resulting in outstanding performance at a low cost. The AD587KR offers superior accuracy and stability compared to most other 10 V references, making it an ideal choice for precision applications.

The device features an industry-standard pinout, allowing for instant upgrades in many systems. It is particularly suited for use as a reference in 8-bit, 10-bit, 12-bit, 14-bit, or 16-bit DACs and successive approximation or integrating ADCs with up to 14 bits of accuracy. The AD587KR provides better performance than standard on-chip references and is known for its low noise and drift characteristics.
