DESCRIPTION
The OPA2694 is a dual, ultra-wideband, low-power, current
feedback operational amplifier f eaturing 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.
