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). 1 8 NC –IN 2 7 +VS +IN 3 6 VOUT –VS 4 5 NC NC = NO CONNECT 1 –VS 2 +IN 3 5 +VS 4 –IN AD8055 Figure 1. N-8 and R-8 Figure 2.

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 …
