DESCRIPTION
The OPA648 is an ultra high bandwidth current feed-
back operational amplifier. The current feedback ar-
chitecture also allows for a very high slew rate, which
gives excellent large signal bandwidth, even at high
gains. The high slew rate and well-behaved pulse
response allow for superior large signal amplification
in a variety of RF, video and other signal processing
applications. Fabricated on an advanced complemen-
tary bipolar process, the OPA648 offers exceptional
performance in monolithic form.
