OPA694
SBOS319C − SEPTEMBER 2004 − REVISED NOVEMBER 2004
Wideband, Low-Power, Current Feedback
Operational Amplifier
FD EATURES
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.
UNITY GAIN STABLE BANDWIDTH: 1.5GHz
HIGH GAIN OF 2V/V BANDWIDTH: 690MHz
LOW SUPPLY CURRENT: 5.8mA

Pb-FREE AND GREEN SOT23-5 PACKAGE
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.
