DESCRIPTION
The OPA4650 is a quad, 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 input bias current allows its use in
high speed integrator applications, while the wide
bandwidth and true differential input stage make it
suitable for use in a variety of active filter applica-
tions. Its low distortion gives exceptional performance
for telecommunications, medical imaging and video
applications.
The OPA4650 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 OPA4650 is also available in single (OPA650)
and dual (OPA2650) configurations.
