PRODUCT DESCRIPTION
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 Ω load,
and 0.02% and 0.1° while driving four video loads (37.5 Ω).
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.
√Hz
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.
