Description

The HFA1245 is a dual, high speed, low power current feedback amplifier built with Intersil's proprietary complementary bipolar UHF-1 process.

The HFA1245 features individual TTL/CMOS compatible disable controls. When pulled low they disable the corresponding amplifier, which reduces the supply current and forces the output into a high impedance state. This feature 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 HFA1245 useful as the A/D driver/multiplexer.

The HFA1245 is a low power, high performance upgrade for the popular Intersil HA5022. For a dual amplifier without disable, in a standard 8 lead pinout, please see the HFA1205 data sheet.
