AD2426WCCSZ-RL | Automotive A²B® Audio Bus Transceiver | In-Vehicle Audio Networking

Product Overview

     The AD2426WCCSZ-RL is an automotive-qualified A²B® (Automotive Audio Bus) transceiver designed to enable high-bandwidth, low-latency audio and data distribution over a single unshielded twisted pair (UTP) cable. It supports bidirectional transmission of I²S/TDM audio, I²C control data, and power over the same cable, significantly reducing wiring complexity, weight, and BOM cost. With robust EMI performance and built-in diagnostics, the device is well suited for modern in-vehicle infotainment and distributed audio architectures.
