Overview
The AD8002ARZ is a dual, low-power, high-speed current feedback amplifier produced by Analog Devices Inc. This amplifier is designed to operate on ±5 V supplies and is notable for its high performance in video and high-speed analog applications. It 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. The AD8002ARZ 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 time.
