ACNW (Analog CMOS Isolation Amplifier Optocoupler) is a series of optocouplers developed by Broadcom that integrates an isolation amplifier with a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) optocoupler. These devices are designed to provide high-precision analogue signal isolation and amplification in a single package.

These optocouplers provide high-linearity amplification of analogue signals across a wide bandwidth, ensuring accurate reproduction of the input signal. ACNW optocouplers are capable of high-speed operation, making them suitable for applications requiring rapid data transmission and precise timing. They also offer high input-to-output isolation voltage, ensuring robust protection against voltage transients and electrical noise. Other features include low power consumption, often exhibit good temperature stability and are available in compact package options, enabling easy integration into space-constrained designs.

Applications of ACNW optocouplers include precision instrumentation, industrial process control, medical equipment, power electronics, and data communication systems, among others. Their integration of isolation and amplification functions, along with high-speed performance and reliable isolation, makes them suitable for applications requiring accurate signal transmission and isolation in demanding environments.
