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.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1. θJA is measured with the component mounted on an evaluation PC board in free air.

2. Output is short circuit protected to ground. Brief short circuits to ground will not degrade reliability, however continuous (100% duty cycle)
output current must not exceed 30mA for maximum reliability.
