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
