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
