GENERAL DESCRIPTION

The AD8002 is a dual, low power, high speed amplifier designed to operate on ±5 V supplies. The AD8002 features unique transimpedance linearization circuitry, which allows the 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 switchers. Additionally, the low distortion and fast settling of the AD8002 make it ideal for buffer high speed analog-to digital converters (ADCs).
