GENERAL DESCRIPTION
The AD8002 is a dual, low power, high speed amplifier designed to operate on ±5 V supplies. The AD8002 features
SIDE 1
unique transimpedance linearization circuitry, which allows the
G = +2 1V STEP
AD8002 to drive video loads with excellent differential gain and phase performance on only 50 mW of power per amplifier. The AD8002 is a current feedback amplifier and features gain flatness of 0.1 dB to 60 MHz while offering differential gain and phase error of 0.01% and 0.02°, which makes the AD8002 ideal for professional video electronics such as cameras and video
