Low Power, ؎5 V Supplies  
5 mA Typ/Amplifier Power Supply Current  
High Output Drive Current: Over 60 mA  
The AD8055 and AD8056 require only 5 mA typ/amplifier of  
supply current and operate on dual 5 V or single +12 V power  
supply, while being capable of delivering over 60 mA of load  
current. All this is offered in a small 8-lead plastic DIP, 8-lead  
SOIC packages, 5-lead SOT-23-5 package (AD8055) and an  
8-lead microSOIC package (AD8056). These features make  
the AD8055/AD8056 ideal for portable and battery powered  
applications where size and power are critical. These amplifiers are  
available in the industrial temperature range of –40°C to +85°C.

The AD8055 (single) and AD8056 (dual) voltage feedback  
amplifiers offer bandwidth and slew rate typically found in cur-  
rent 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 excel-  
lent overall performance. For video applications, their differen-  
tial 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 (37.5 ).  
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.
