APPLICATIONS

8-Lead Plastic DIP, SOIC, and /H9262SOIC OUT1 –IN1 +IN1 OUT2 –IN2 +IN2 AD8002 PRODUCT DESCRIPTION The AD8002 is a dual, low-power, high-speed amplifier designed to operate on±5 V supplies. The AD8002 features unique trans- impedance linearization circuitry. This allows it 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°. This makes the AD8002 ideal for professional video electronics such as cameras and video switchers. Additionally, the AD8002’s low distortion and fast settling make it ideal for buffer high-speed A-to-D converters. The AD8002 offers low power of 5.5 mA/amplifier max (V S = ± 5 V) and can run on a single 12 V power supply, while capable of delivering over 70 mA of load current. It is offered in an 8-lead plastic DIP, SOIC, and µSOIC package. These features make this amplifier ideal for portable and battery-powered applica tions where size and power are critical. The outstanding bandwidth of 600 MHz along with 1200 V/ µs of slew rate make the AD8002 useful in many general purpose high speed applications where dual power supplies of up to ± 6 V and single supplies from 6 V to 12 V are needed. The AD8002 is available in the industrial temperature range of –40°C to +85 °C. 1M 10M 1G 100M –0.5 –0.1 –0.2 –0.3 –0.4 0.1 NORMALIZED FLATNESS – dB FREQUENCY – Hz NORMALIZED FREQUENCY RESPONSE – dBSIDE 1 SIDE 2 SIDE 1 SIDE 2 G = +2 RL = 100/H9024 VIN = 50mV Figure 1.
