Data Sheet June 2000

450MHz, Low Power, Video Operational
Amplifier with Programmable Output
Disable

The HFA1149 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 HFA1149 incorporates an output disable pin which is
TTL/CMOS compatible, and user programmable for polarity
(active high or low). This feature eliminates the inverter
required between amplifiers in multiplexer configurations.
The ultra-fast (12ns/20ns) disable/enable times make the
HFA1149 the obvious choice for pixel switching and other
high speed multiplexingapplications.TheHFA1149isahigh
performance, pin compatible upgrade f or the popular HA-5020
and HFA1145, as well as the CLC410.

For a comparably performing op amp without an output
disable, please refer to the HFA1109 data sheet.
