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/µs 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
75Ω cables when using the amplifier as a line driver in
video routers, distribution amplifiers, and analog and
digital communications equipment.
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.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes
could cause the device not to meet its published specifications.
