HFA1145 Description

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.
