DESCRIPTION
The OPA650 is a low power, wideband voltage feed-
back operational amplifier. It features a high band-
width of 560MHz 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 OPA650 is internally compensated for unity-gain
stability. This amplifier has a fully symmetrical differ-
ential input due to its “classical” operational amplifier
circuit architecture. Its unusual combination of speed,
accuracy and low power make it an outstanding choice
for many portable, multi-channel and other high speed
applications, where power is at a premium.
The OPA650 is also available in dual (OPA2650) and
quad (OPA4650) configurations.
