Suitable for developing DSP-based audio systems


Analog Devices (ADI) announced on the 9th that it is launching an audio system that accelerates the development of various digital audio devices.

ADI's audio system consists of the SHARC audio module main board (ADZS-SC589-MINI, $195), the audio project pin board (ADZS-AUDIOPROJECT, $95), and the A ² B Class-D amplifier module (ADZS-AUDIOA2BAMP, $95), and can be used to develop audio FX processors, multi-channel audio systems, MIDI synthesizers, and other DSP-based audio systems.

The SHARC audio module main board features the ADSP-SC589 floating-point SHARC processor and the AD2428 low-latency A ^/ B audio bus transceiver, and comes with a free CrossCore Embedded Studio license and ICE-1000 emulator for debugging.

The audio project pin board features three MIDI 5-pin ports and two 1/4-inch stereo jacks for input and output, four push buttons for programming and external connectivity, and three dials that connect to the housekeeping ADC of the SHARC audio module.

A ² B Class-D amplifier module is a two-wire twisted pair It can receive digital audio data from a PDM microphone or serial TDM source on the main board or another connected A ² B node using the configured A ² B bus. It also has two SSM3582 high-efficiency 4-input 4-output Class-D amplifiers that amplify the data and output it directly to passive speakers.

Providing high-fidelity multi-channel digital audio with low, uniform latency to a fully synchronized, distributed audio system, this audio system is ideal for rapid prototyping, evaluation projects, demonstrations, and educational applications.
