Overview
The AD8002ARM-REEL, produced by Analog Devices Inc., is a dual, low-power, high-speed current feedback amplifier. This component is designed to operate on ±5 V supplies and is particularly suited for applications requiring high bandwidth, low power consumption, and excellent differential gain and phase performance. The AD8002 features unique transimpedance linearization circuitry, enabling it to drive video loads with minimal distortion and high accuracy. It is ideal for professional video electronics, such as cameras and video switchers, as well as for buffering high-speed analog-to-digital converters (ADCs).
