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.
