Overview
The AD8002ARM, produced by Analog Devices Inc., is a dual, low-power, high-speed current feedback amplifier. This amplifier is designed to operate on ±5 V supplies and is particularly suited for applications requiring excellent video specifications and high-speed performance. The AD8002 features unique transimpedance linearization circuitry, enabling it to drive video loads with outstanding 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).
