DESCRIPTION

The OPA641 is an extremely wideband operational

amplifier featuring low noise, high slew rate and high

spurious free dynamic range.

The OPA641 is conservatively compensated for sta-

bility in gains of 2 or greater. This amplifier has a fully

symmetrical differential input due to its “classical”

operational amplifier circuit architecture. This allows

the OPA641 to be used in all op amp applications

requiring high speed and precision.

Low noise, wide bandwidth, and high linearity make

this amplifier suitable for a variety of RF, video, and

imaging applications.
