Analog Devices revolutionerer audio-oplevelsen i nye køretøjer

Analog Devices er nu klar med A²B 2.0, der åbner mulighed for at levere en bedre audiooplevelse inde i bilerne gennem support af højere båndbredde og bedre Ethernet integration (in english).

Analog Devices has announced its A²B 2.0 is now fully released to production. As the next evolution of ADI's A²B technology, A²B 2.0 is designed to help automotive OEMs (original equipment manufacturers) and Tier 1 suppliers deliver richer in cabin audio experiences through greater bandwith and Ethernet integration, while preserving the low latency, simple architecture that has defined A²B for years.

Over the past decade, A²B has been broadly adopted in the automotive industry, with hundreds of millions of nodes on the road from over 35 automotive manufacturers, establishing a strong foundation for the next evolution of the technology.

Built for applications where low and deterministic latency is a key system requirement, A²B was designed to support demanding use cases such as road-noise cancellation and in car communications through a simple, flexible, and cost effective approach to audio connectivity. Its single main, multiple sub node daisy chain architecture reduces wiring complexity and associated costs by up to 75%. The straightforward architecture with zero software overhead also lowers overall development time and investment for OEMs and Tier 1 suppliers.

A²B’s momentum is reinforced by an ecosystem that spans OEMs, silicon partners, and original design manufacturers (ODMs), supported by an expansive set of development and test tools that accelerate time to market.

The shift to modern vehicle networks and Software-Defined Vehicle (SDV) architectures

As vehicles transition to software defined architectures, in cabin features are increasingly delivered and improved through software, raising the bar for deterministic, high bandwidth connectivity that can integrate cleanly with modern in vehicle networks. As in cabin technology becomes a key differentiator for automakers, expectations for premium audio and infotainment continue to rise, ultimately driving demand for higher bandwidth, advanced connectivity, and seamless integration with today’s vehicle networks.

- Audio is central to how drivers perceive refinement, safety, and responsiveness inside the vehicle, especially as cabins become more software defined. In this new era, engineers need audio connectivity that integrates cleanly with the broader vehicle network. A²B 2.0 delivers higher bandwidth, low latency and Ethernet tunneling without adding architectural complexity, says Yasmine King, Corporate Vice President, Head of Automotive Business Unit, ADI.
