HFA1145
330MHz, Low Power, Current Feedback
Video Operational Amplifier with Output
Disable
The HFA1145 is a high speed, low power current feedback
amplifier built with Intersil’s proprietary complementary
bipolar UHF-1 process.
This amplifier features a TTL/CMOS compatible disable
control, pin 8, which when pulled low reduces the supply
current and forces the output into a high impedance state.
This allows easy implementation of simple, low power video
switching and routing systems. Component and composite
video systems also benefit from this op amp’s excellent gain
flatness, and good differential gain and phase specifications.
Multiplexed A/D applications will also find the HFA1145
useful as the A/D driver/multiplexer.
The HFA1145 is a low power, high performance upgrade for
the CLC410.

HFA11XXEVAL DIP Evaluation Board for High Speed Op Amps
Note: Requires a SOIC-to-DIP adapter. See
“Evaluation Board” section inside.
NOTE: 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.
*Pb-free PDIPs can be used for through hole wave solder processing
only. They are not intended for use in Reflow solder processing
applications.
