Overview
The AD8002AR-REEL7, 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 speed and low power consumption. The AD8002 features unique transimpedance linearization circuitry, which enables it to drive video loads with excellent differential gain and phase performance while consuming only 50 mW of power per amplifier. This makes it ideal for professional video electronics, such as cameras and video switchers, as well as for buffering high-speed analog-to-digital converters (ADCs).
