PRODUCT 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. 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 (VS = ±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 applications 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.
