•

UNITY GAIN STABLE BANDWIDTH: 1.5GHz

•

HIGH GAIN OF 2V/V BANDWIDTH: 690MHz

The OPA694 is an ultra-wideband, low-power, current

feedback operational amplifier featuring high slew

•

LOW SUPPLY CURRENT: 5.8mA

rate and low differential gain/phase errors. An

•

HIGH SLEW RATE: 1700V/msec

improved output stage provides ±80mA output drive

•

HIGH FULL-POWER BANDWIDTH: 675MHz

with < 1.5V output voltage headroom. Low supply

current

meets

the

•

LOW DIFFERENTIAL GAIN/PHASE:

requirements of high-density video routers. Being a

0.03%/0.015°

current feedback design, the OPA694 holds its

bandwidth to very high gains—at a gain of 10, the

OPA694 will still provide 200MHz bandwidth.

APPLICATIONS

RF applications can use the OPA694 as a low-power
