HFA1105
330MHz, Low Power, Current Feedback
Video Operational Amplifier
The HFA1105 is a high speed, low power current feedback
amplifier built with Intersil’s proprietary complementary
bipolar UHF-1 process.
This amplifier features an excellent combination of low
power dissipation (58mW) and high performance. The slew
rate, bandwidth, and low output impedance (0.08
) make
this amplifier a good choice for driving Flash ADCs.
Component and composite video systems also benefit from
this op amp’s excellent gain flatness, and good differential
gain and phase specifications. The HFA1105 is ideal for
interfacing to Intersil’s line of video crosspoint switches
(HA4201, HA4600, HA4314, HA4404, HA4344), to create
high performance, low power switchers and routers.
The HFA1105 is a low power, high performance upgrade for
the CLC406. For a comparable amplifier with output disable
or output limiting functions, please see the data sheets for
the HFA1145 and HFA1135 respectively.
For Military grade product, please refer to the HFA1145/883
data sheet

NOTES:
1. Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and
100% matte tin plate termination finish, which are RoHS
compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
2. Requires a SOIC-to-DIP adapter. See “Evaluation Board” section
inside.
