Overview
The AD8002AR-REEL, produced by Analog Devices Inc., is a dual, low-power, high-speed current feedback amplifier. It is designed to operate on ±5 V supplies and 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 amplifier is ideal for professional video electronics, such as cameras and video switchers, as well as for buffering high-speed analog-to-digital converters (ADCs) due to its low distortion and fast settling times.
