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.
