DESCRIPTION
The OPA658 is an ultra-wideband, low power current feed-
back video operational amplifier featuring high slew rate and
low differential gain/phase error. The current feedback de-
sign allows for superior large signal bandwidth, even at high
gains. The low differential gain/phase errors, wide bandwidth
and low quiescent current make the OPA658 a perfect
choice for numerous video, imaging and communications
applications.
The OPA658 is optimized for low gain operation and is also
available in dual (OPA2658) configurations.
