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.

(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not supported.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
