The OPA623 operates from a
±
5V supply, is speci-
fied for the extended industrial temperature range
(–40
°
C to +85
°
C), and is available in plastic SO-8
and 8-pin plastic DIP packages.
The OPA623 is a current-feedback operational ampli-
fier designed for precision wide-bandwidth systems
including high-resolution video, RF and IF circuitry,
and communications equipment.
The new circuit design, together with the complemen-
tary bipolar process, achieves performance pre-
viously unattainable in monolithic integrated circuit
technology.
The current-feedback op amp is optimized for wide
bandwidth, excellent pulse response, gain flatness,
low distortion, and operation at a low quiescent cur-
rent of
±
4mA.
It provides a 350MHz large-signal bandwidth at
2.8Vp-p output voltage, as well as a 2100V/
μ
s slew
rate. The gain flatness of 0.05dB over a 30MHz
bandwidth makes it suitable for HDTV designs. An-
other feature of the op amp is its high output current
of
±
70mA, enabling it to drive two back-terminated
75
cables when using the amplifier as a line driver in
video routers, distribution amplifiers, and analog and
digital communications equipment.
