HFA1405
September 1998 File Number 3604.5
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
1700V/µs slew rate,ononly58mWofquiescentpower.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
when driving two back terminated cables (R
= 150Ω), and degrades only slightly
L
= 75Ω). RGB
L
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.

NOTES:
1. θJA is measured with the component mounted on an evaluation PC board in free air.
2. Output is shortcircuit protected toground.Brief short circuitstoground will notdegrade reliability, howevercontinuous(100% duty cycle)output
current must not exceed 30mA for maximum reliability.

NOTES:
3. The optimum feedback resistor depends on closed loop gain and package type. The following resistors were used for the PDIP/SOIC characterization: AV= -1, RF= 310Ω/360Ω; AV= +2, RF= 402Ω/510Ω; AV= +6, RF= 500Ω/500Ω. See the Application Information section for more
information.
4. Test Level: A. Production Tested; B. Typical or Guaranteed Limit Based on Characterization; C. Design Typical for Information Only.
5. See Typical Performance Curves for more information.
6. Undershoot dominates for output signal swings below GND (e.g., 2V
), yielding a higher overshoot limit compared to the V
