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/

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

75

Ω cables when using the amplifier as a line driver in

video routers, distribution amplifiers, and analog and

digital communications equipment.
