HFA1109

450MHz, Low Power, Current Feedback Video Operational Amplifier

FN4019

Rev.5.00

April 23, 2007

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..

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.
