The HFA1145/883 is a high speed, low power current

feedback amplifier built with Intersil’ 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 HFA1145/883

useful as the A/D driver/multiplexer.

The HFA1145/883 is a low power, high performance upgrade

for the CLC410.

Applications

• Multiplexed Flash A/D Driver

• RGB Multiplexers / Preamps for Multimedia Systems

• Video Switching and Routing

• Pulse and Video Amplifiers

• Wideband Amplifiers

• RF/IF Signal Processing

• Medical Imaging Systems
