AD8001

800兆赫， 50毫瓦电流反馈放大器 800 MHz, 50 mW Current Feedback Amplifier

Product Details

The is a low power, high speed amplifier designed to operate on ±5 V supplies. The AD8001 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. The AD8001 is a current feedback amplifier and features gain flatness of 0.1 dB to 100 MHz while offering differential gain and phase error of 0.01% and 0.025°. This makes the AD8001 ideal for professional video electronics such as cameras and video switchers. Additionally, the AD8001"s low distortion and fast settling make it ideal for buffer high speed A-to-D converters.

The AD8001 offers low power of 5.5 mA max VS = ±5 V and can run on a single +12 V power supply, while being capable of delivering over 70 mA of load current. All this is offered in a small 8-pin DIP or 8-pin SOIC package. These features make this amplifier ideal for portable and battery powered applications where size and power is critical.

The outstanding bandwidth of 800 MHz along with 1200 V/µs of slew rate make the AD8001 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 AD8001 is available in the industrial temperature range of -40°C to +85°C.

An evaluation board is available for this product and may be ordered using the following product number: AD8001-EB. Schematic and layout for this evaluation board is contained in the product datasheet.
