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.

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 Ω load and 0.02% and 0.1° while driving four video loads
(37.50 Ω).
