DESCRIPTION

The OPA640 is an extremely wideband operational

amplifier featuring low noise, high common-mode

rejection and high spurious free dynamic range.

The OPA640 is internally compensated for unity-gain

stability. This amplifier has a fully symmetrical differ-

ential input due to its 鈥渃lassical鈥?operational amplifier

circuit architecture. This allows the OPA640 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 and video

applications.
