A2B Audio Bus: Two Alternative Power Schemes

In the second article about the latest generation A2B technology from Analog Devices - expanded with the release of the AD2437 chip - Brewster LaMacchia explores the latest possibilities for audio applications in many other areas other than automotive audio. After reviewing the three generations of A2B technology, LaMacchia expands on the alternative power schemes that deserve some investigation for multichannel digital audio applications. This article was originally published in audioXpress, August 2024.

In this article, Brewster LaMacchia concludes his series on Automotive Audio Bus (A2B) applications (not just for automotive). After an introduction to the properties of this locally networked audio transport, a look at A2B system design, and A2B data transport and interface, in Part 4, the author looks at systems and tools that are available to speed prototyping and evaluation.

This is the first article in a four-part series about Analog Devices' A2B or Automotive Audio Bus, a digital audio bus technology originally developed for automotive requirements that is finding interesting design possibilities in other audio applications. This first article discusses the main features of A2B, and its use with I2S and PDM interfaces, before exploring the technical underpinnings of the A2B bus design and creating systems with the development tools available. This article was originally published in audioXpress, October 2020.

Audinate, the developer of the industry-leading Dante AoIP networking technology, and Analog Devices have collaborated to introduce the availability of Dante Embedded Platform for ADI’s SHARC audio digital signal processors. This means that manufacturers using SHARC DSPs are now able to benefit from Dante audio-over-IP as on-chip software and a streamlined product development cycle.

Analog Devices announced the availability of its new SHARC Audio Module (ADZS-SC589-MINI), a hardware/software platform that facilitates efficient product prototyping, development, and production of a variety of digital audio products. Delivering an innovative combination of high-performance audio signal processing components and a comprehensive software development environment, the SHARC Audio Module is ideal for effects processors, multi-channel audio systems, MIDI synthesizers, and many other DSP-based audio projects.
