Analog Devices offers three enhanced Automotive Audio Bus (A2B) transceivers that achieve the unparalleled ability to tailor system-level performance to even the most stringent EMC demands. The new AD242x series provides configurable transmit power levels, allowing the developer to match system performance to specific OEM EMC requirements – a key design criterion for all feature-rich automotive infotainment systems. The transceivers also enable expanded use cases for microphone connectivity and significantly decrease cabling complexity by distributing audio and control data plus clock and power over a single, unshielded twisted-pair wire. These features significantly lower system cost and are excellent for emerging multi-mic applications such as road noise cancellation, in-car communications, and autonomous driving. The new devices are fully pin-compatible with existing series members, simplifying upgrade and speeding time to market.
“The A2B technology has proven to be a simple and cost-effective digital audio interconnect solution with the scalability that enables HARMAN to deliver a broad range of differentiated systems across multiple vehicle platforms,” said Darby Hadley, vice president Global Engineering, Car Audio SBU for HARMAN Lifestyle Audio Division. “The AD242x series offers a seamless and fast time-to-market upgrade path for our existing A2B car audio solutions.”
The AD2426W, AD2427W and AD2428W are fully compliant with all relevant automotive EMC, EMI and ESD requirements, are fully AEC-Q100 qualified, and operate over the extended automotive temperature range (-40C to +105C).
