FN3605.6
Dual, 425MHz, Low Power, Video
Operational Amplifier
The HFA1205 is a dual, high speed, low power current
feedback amplifier built with Intersil’s proprietary
complementary bipolar UHF-1 process.
These amplifiers deliver 425MHz bandwidth and 1350V/µs
slew rate, on only 60mW of quiescent power. They are
specifically designed to meet the performance, power, and
cost requirements of high volume video applications. The
excellent gain flatness and differential gain/phase
performance make these amplifiers well suited for
component or composite video applications. Video
performance is maintained even when driving a back
terminated cable (R_L = 150Ω), and degrades only slightly
when driving two back terminated cables (R_L = 75Ω). RGB
applications will benefit from the high slew rates, and high
full power bandwidth.
The HFA1205 is a pin compatible, low power, high
performance upgrade for the popular Intersil HA5023. For a
dual amplifier with output disable capability, please see the
HFA1245 data sheet.
