AD2428

ADZS-AD2428MINI is a low-cost, mini break-out board which can interface with EV-SOMCRR-EZKIT (via a 100-pin connector) or any custom board (via a 32 pin 0.1" header). It supports master and remote node capability as well as bus and local power configurations.

An Automotive Audio Bus (A²B^®) system consists of a single master and at least one slave, where the transceiver at the host controller is the master. The master transceiver generates clock, synchronization, and framing for all slave nodes and is programmable over a control bus (I²C) for configuration and readback. An extension of this control bus is embedded in the A²B data stream, which enables the host to directly access slave transceiver registers and any I²C-connected peripherals on slave nodes.

Transceivers can connect directly to PDM microphones and to numerous peripherals via I²C and a multichannel I²S/TDM interface. Finally, the transceiver also supports an A²B bus powering feature, where the master node supplies voltage and current to the slave nodes over the same daisy-chained, twisted pair wire cable as used for the communication link, thus eliminating the need for a power supply on bus-powered slave nodes. Due to the numerous configurations that are possible for a given A²B system, there are several evaluation platforms that can be used in combination to verify system operation, as summarized in the table below.

The A²B Class-D Amplifier Module leverages ADI's low-latency A²B audio bus technology, featuring an AD2428W A²B transceiver (serving as an A²B slave) that accepts audio over the A²B bus from a connected A²B node in the system. The ADZS-AUDIOA2BAMP Module drives the received A²B data to a pair of high-efficiency, digital input, stereo SSM3582 class-D audio amplifiers. Audio is transmitted digitally to the amplifier, minimizing the possibility of signal corruption in digital environments. See the SSM3582 data sheet for more information.

As the A²B Class-D Amplifier Module is an A²B slave node, it must be incorporated into an A²B system with a master node, such as the SHARC^® Audio Module or the A²B master evaluation board. Connect the A²B Class-D Amplifier Module to the system using the included A²B twisted-wire-pair cable.
