OPA648

ULTRA-WIDEBAND CURRENT

FEEDBACK OPERATIONAL AMPLIFIER

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.
