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.

WIDEBAND VIDEO LINE DRIVER  
The OPA694 is available in an industry-standard pinout in  
both SO-8 and SOT23-5 packages.
