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.
