HFA1405

Quad, 560MHz, Low Power, Video

Operational Amplifier

The HFA1405 is a quad, high speed, low power current

feedback amplifier built with Intersil’s proprietary

complementary bipolar UHF-1 process.

These amplifiers deliver up to 560MHz bandwidth and

2500V/

µs 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 back

applications will benefit from the high slew rates, and high

full power bandwidth.

The HFA1405 is a pin compatible, low power, high

performance upgrade for the popular Intersil HA5025, and

for the CLC414 and CLC415.
