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 profes-

sional 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 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-lead plastic DIP or 8-lead 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.

PRODUCT DESCRIPTION

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-purpose
