It is offered in 8-lead SOIC and MSOP packages. These features make this APPLICATIONS amplifier ideal for portable and battery-powered applications Analog-to-digital drivers where size and power are critical. Video line drivers The bandwidth of 600 MHz along with 1200 V/s of slew rate Differential line drivers make the AD8002 useful in many general-purpose high speed Professional cameras applications where dual power supplies of up to 6 V and single Video switchers supplies from 6 V to 12 V are needed. The AD8002 is available Special effects in the industrial temperature range of 40C to +85C. RF receivers GENERAL DESCRIPTION The AD8002 is a dual, low power, high speed amplifier designed to operate on 5 V supplies. The AD8002 features SIDE 1 G = +2 1V STEP 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 SIDE 2 for professional video electronics such as cameras and video 200mV 5ns switchers. Additionally, the low distortion and fast settling of the AD8002 make it ideal for buffer high speed analog-to- Figure 2. 1 V Step Response, G = +1 digital converters (ADCs). Rev.
