Analog Devices, Inc. (ADI) introduced today a full audio system that features the SHARC^® Audio Module (SAM) for the creation of digital audio devices, including audio FX processors, multi-channel audio systems, MIDI synthesizers, and other DSP-based audio systems. SAM includes the dual-SHARC+ core ADSP-SC589 audio processor SoC (with an integrated Arm^® Cortex^®-A5 core) and leverages Analog Devices’ A²B audio bus technology. In addition to the main SHARC audio module board, ADI offers daughter boards to provide added functionality to the main board and expand the audio system. The Audio Project Fin board mates directly to the main board, providing MIDI input/output as well as pushbuttons and potentiometers to modify audio effects. The A²B Amplifier Module features two high-efficiency Class-D amplifiers to output digital audio data received over the twisted-wire pair A²B bus from PDM microphones and/or serial TDM sources on the main board (or another connected A²B node).

This complete audio system delivers high-fidelity multichannel digital audio with low and deterministic latency to a fully synchronized distributed audio system. The system is ideal for fast prototyping, evaluation projects, demonstrations, and educational applications. It enables users to realize a shorter time to market with a “ready to go” prototype system that provides a comprehensive hardware and software solution.
