DESCRIPTION
The OPA694 is an ultra-wideband, low-power, current
feedback operational amplifier featuring high slew rate and
low differential gain/phase errors. An improved output
stage provides ±80mA 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 OPA694
holds its bandwidth to very high gains—at a gain of 10, the
OPA694 will still provide 200MHz bandwidth.
RF applications can use the OPA694 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 OPA694 is available in an industry-standard pinout in
both SO-8 and SOT23-5 packages.
