HFA1305
Triple, 675MHz, Low Power, Video
Operational Amplifier
The HFA1305 is a triple, high speed, low power current
feedback amplifier built with Intersil’s proprietary
complementary bipolar UHF-1 process.
These amplifiers deliver up to 675MHz bandwidth and
2500V/
μ
s slew rate, on only 58mW 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 double
terminated cable (R
L
= 150
), and degrades only slightly
when driving two double terminated cables (R
L
= 75
). RGB
applications will benefit from the high slew rates, and high
full power bandwidth.
The HFA1305 is a pin compatible, low power, high
performance upgrade for the popular Intersil HA5013, and
for the AD8073 and CLC5623, in
±
5V applications.
