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.
