The OPA2694 is a dual, ultra-wideband, low-power, current feedback operational amplifier featuring high slew rate and low differential gain/phase errors. An improved output stage provides ±70mA output drive with < 1.5V output voltage headroom. Low supply current with > 500MHz bandwidth meets the requirements of high density video routers. Being a current feedback design, the OPA2694 holds its bandwidth to very high gains—at a gain of 10, the OPA2694 will still provide > 200MHz bandwidth.

RF applications can use the OPA2694 as a low-power SAW pre-amplifier. Extremely high 3rd-order intercept is provided through 70MHz at much lower quiescent power than many typical RF amplifiers.

The OPA2694 is available in an industry-standard pinout in an SO-8 package.
