PRODUCT DESCRIPTION
The AD8072 (dual) and AD8073 (triple) are low cost, current
feedback amplifiers intended for high volume, cost sensitive
applications. In addition to being low cost, these amplifiers
deliver solid video performance into a 150
load while consuming
only 3.5 mA per amplifier of supply current. Furthermore, the
AD8073 is three amplifiers in a single 14-lead narrow-body
SOIC package. This makes it ideal for applications where small
size is essential. Each amplifier’s inputs and output are acces-
sible providing added gain setting flexibility.
These devices provide 30 mA of output current per amplifier,
and are optimized for driving one back terminated video load
(150
) each. These current feedback amplifiers feature gain
flatness of 0.1 dB to 10 MHz while offering differential gain and
phase error of 0.05% and 0.1
°. This makes the AD8072 and
AD8073 ideal for business and consumer video electronics.
Both will operate from a single 5 V to 12 V power supply. The
outputs of each amplifier swing to within 1.3 volts of either sup-
ply rail to accommodate video signals on a single 5 V supply.
The high bandwidth of 100 MHz, 500 V/
s of slew rate, along
with settling to 0.1% in 25 ns, make the AD8072 and AD8073
useful in many general purpose, high speed applications where a
single 5 V or dual power supplies up to
±6 V are needed. The
AD8072 is available in 8-lead plastic DIP, SOIC, and
SOIC
packages while the AD8073 is available in 14-lead plastic DIP and
SOIC packages. Both operate over the commercial temperature
range of 0
°C to 70°C. Additionally, the AD8072ARM operates
over the industrial temperature range of –40
°C to +85°C.
