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.  
0.02° differential phase error  
Drives 4 video loads (37.5 V) with 0.02% differential  
Gain and 0.1° differential phase  
Low power, 5 V supplies 5 mA typ/amplifier power  
supply current  
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.  
High output drive current: over 60 mA

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).
