DESCRIPTION

The OPA2650 is a dual, low power, wideband voltage

feedback operational amplifier. It features a high band-

width of 360MHz as well as a 12-bit settling time of

only 20ns. The low distortion allows its use in commu-

nications applications, while the wide bandwidth and

true differential input stage make it suitable for use in

a variety of active filter applications. Its low distortion

gives exceptional performance for telecommunica-

tions, medical imaging and video applications.

The OPA2650 is internally compensated for unity-

gain stability. This amplifier has a fully symmetrical

differential input due to its “classical” operational

amplifier circuit architecture. Its unusual combination

of speed, accuracy and low power make it an outstand-

ing choice for many portable, multi-channel and other

high speed applications, where power is at a premium.

The OPA2650 is also available in single (OPA650)

and quad (OPA4650) configurations.
