HFA1109
450MHz, Low Power, Current Feedback
Video Operational Amplifier
The HFA1109 is a high speed, low power, current feedback
amplifier built with Intersil’s proprietary complementary
bipolar UHF-1 process. This amplifier features a unique
combination of power and performance specifically tailored
for video applications.
The HFA1109 is a standard pinout op amp. It is a higher
performance, drop-in replacement (no feedback resistor
change required) for the CLC409.
If a comparably performing op amp with an output disable
function (useful for video multiplexing) is required, please
refer to the HFA1149 data sheet..

DIP Evaluation Board for High Speed Op Amps
NOTES:
1. Intersil Pb-free plus anneal products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
2. Requires a SOIC-to-DIP adapter. See “Evaluation Board” section
inside.
