AD8011

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 amplifier. It also can be used to replace high speed

amplifiers consuming more power. The AD8011 is a current feed-

back 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-, and 12-bit A-to-D converters.

The AD8011 offers very low power of 1 mA maximum and can

run on single 5 V to 12 V supplies. All this is offered in a small

8-lead PDIP 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.
