PRODUCT DESCRIPTIONThe 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 20ns settling
time, make them useful for a variety of high speed applications.
The AD8055 and AD8056 require only 5mA 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 amplifiersare
available in the industrial temperature range of –40°C to +85°C.

NOTESStresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.Specification is for device in free air:
8-Lead Plastic DIP Package: θJA = 90°C/W
8-Lead SOIC Package: θJA = 155°C/W
5-Lead SOT-23-5 Package: θJA = 240°C/W
8-Lead microSOIC Package: θJA = 200°C/W
MAXIMUM POWER DISSIPATIONThe maximum power that can be safely dissipated by the AD8055/
AD8056 is limited by the associated rise in junction temperature.
The maximum safe junction temperature for plastic encapsu-
lated devices is determined by the glass transition temperature
of the plastic, approximately +150°C. Exceeding this limit tem-
porarily may cause a shift in parametric performance due to a
change in the stresses exerted on the die by the package. Exceeding
a junction temperature of +175°C for an extended period can
result in device failure.
While the AD8055/AD8056 are internally short circuit protected,
this may not be sufficient to guarantee that the maximum junc-
tion temperature (+150°C) is not exceeded under all conditions.
To ensure proper operation, it is necessary to observe the maxi-
mum power derating curves.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8055/AD8056 features proprietary ESD protection circuitry, permanent dam-
age may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.
