DESCRIPTION
The OPA4658 is a quad ultra-wideband, low power
current feedback video operational amplifier featuring
high slew rate and low differential gain/phase error.
The current feedback design allows for superior large
signal bandwidth, even at high gains. The low differ-
ential gain/phase errors, wide bandwidth and low
quiescent current make the OPA4658 a perfect choice
for numerous video, imaging and communications
applications.
The OPA4658 is internally compensated for stability in
gains of 2 or greater. The OPA4658 is also available in
dual (OPA2658) and single (OPA658) configurations.
