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.
