Their 0.1 dB flatness out to 40 MHz, wide bandwidth out to
300 MHz, along with 1400 V/µs slew rate and 20 ns settling
time, make them useful for a variety of high speed applications.

The AD8055 and AD8056 require only 5 mA typ/amplifier of
supply current and operate on a dual ±5 V or a single +12 V
power supply, while capable of delivering over 60 mA of load
current. The AD8055 is available in a small 8-lead PDIP, an 8-lead
SOIC, and a 5-lead SOT-23, while the AD8056 is available in an
8-lead MSOP. These features make the AD8055/AD8056 ideal
for portable and battery-powered applications where size and
power are critical. These amplifiers in the R-8, N-8, and RM-8
packages are available in the extended temperature range of
−40°C to +125°C.

GENERAL DESCRIPTION
The AD8055 (single) and AD8056 (dual) voltage feedback
amplifiers offer bandwidth and slew rate typically found in
current feedback amplifiers. Additionally, these amplifiers are
easy to use and available at a very low cost.
Despite their low cost, the AD8055 and AD8056 provide
excellent overall performance. For video applications, their
differential gain and phase error are 0.01% and 0.02° into a
150  load and 0.02% and 0.1° while driving four video loads
(37.50 ).
