Description
AI
The Automotive Audio Bus®(A2B®) is an innovative technology that reduces system cost, weight, and design complexity by distributing audio and control data, together with clock and power over a single, low-cost, unshielded twisted pair cable. The AD2425W is an enhanced A2B transceiver offering an expanded feature set while retaining complete compatibility with existing AD241x devices. The AD2425W is fully configurable supporting both master and slave functionality.The AD2425W is targeted for use in wiring intensive applications where reducing the weight or complexity of existing cable harnesses is a primary system design objective. These applications include Premium Audio Systems, Active Noise Cancellation, and In-Car Communications.ApplicationsAutomotive audio communication linkActive noise cancellationMicrophone arrays for hands free and in car communication
