Overview
The AD8018ARUZ-REEL, produced by Analog Devices Inc., is a high-performance, dual current feedback amplifier designed specifically for xDSL (Digital Subscriber Line) applications. This component is optimized for high-output current and low distortion, making it ideal for single-supply xDSL modems where maximum reach and signal integrity are crucial. The AD8018 features a novel, two-stage current feedback architecture with a patent-pending rail-to-rail output stage, enabling it to deliver 400 mA of output current while maintaining low distortion levels.
