May 1, 2026 /SemiMedia/ — Analog Devices, Inc. said its A²B 2.0 automotive audio bus is now in full production, bringing higher bandwidth and Ethernet support to next-generation vehicle platforms.

The new version builds on A²B technology, which has been widely used in the automotive sector over the past decade, with deployment across dozens of carmakers and large volumes already in the field.

A²B is known for its low and predictable latency, making it suitable for applications such as in-car communication and noise control. Its daisy-chain setup, with one main node and multiple sub-nodes, helps reduce wiring and system cost.

With vehicles moving toward software-defined designs, in-cabin systems now require faster data transfer and better integration with vehicle networks. Audio and infotainment features are becoming key factors for carmakers, increasing the need for higher bandwidth and stable connectivity.

A²B 2.0 addresses these changes by increasing bandwidth up to 98.3 Mbps in full duplex mode. It can support a large number of audio channels, allowing more complex sound system designs inside the vehicle.

The platform also adds Ethernet tunneling through an OASPI interface, making it easier to connect with modern in-vehicle networks. Higher integration helps reduce external components, lowering overall system cost.

At the same time, the solution keeps low latency, around 62 microseconds, and maintains a simple structure for easier system design. It is also compatible with existing A²B 1.0 cabling, allowing carmakers to upgrade without major redesign.

A2B 2.0 is now fully released to production. For more information, please visit https://www.analog.com/en/solutions/a2b-automotive-audio-bus.html?adicid=pr_ww-_a2b__newswire_Auto_042126
