HFA1109 Description

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.
