pose amplifier. It also can be used to replace high speed amplifiers consuming more power. The AD8011 is a current feedback amplifier and features gain flatness of 0.1 dB to 25 MHz while offering differential gain and phase error of 0.02% and 0.06° on a single +5 V supply. This makes the AD8011 ideal for professional video electronics such as cameras, video switchers or any high speed portable equipment. Additionally, the AD8011’s low distortion and fast settling make it ideal for buffering high speed 8-, 10-, 12-bit A-to-D converters.

The AD8011 is a very low power, high speed amplifier designed to operate on +5 V or ±5 V supplies. With wide bandwidth, low distortion and low power, this device is ideal as a general pur-

The AD8011 offers very low power of 1 mA max and can run on single +5 V to +12 V supplies. All this is offered in a small 8-pin DIP or 8-pin SOIC package. These features fit well with portable and battery powered applications where size and power are critical. The AD8011 is available in the industrial temperature range of –40°C to +85°C.
