330MHz, Low Power, Current Feedback Video Operational Amplifier with Output

Disable

DATASHEET

FN3955

Rev 5.00

July 15, 2015

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.

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.
