The transceivers offers configurable transmit power levels, enabling the developer to match system performance to specific OEM EMC requirements, which is a key design criterion for all feature-rich automotive infotainment systems. The transceivers also allow expanded use cases for microphone connectivity, significantly reducing cabling complexity by distributing audio and control data, plus clock and power, over a single, unshielded twisted-pair wire to lower system cost and to meet emerging multi-mic applications such as road noise cancellation, in-car communications, and autonomous driving.

The AD2426W, AD2427W and AD2428W are pin-compatible with existing series members to simplify upgrades and speed time to market.

The A²B technology is a digital audio interconnect that offers a deterministic, scalable and cost-effective means to address the rigorous performance requirements of next generation, latency-sensitive audio and voice applications, explains the company. The enhanced AD242x devices are capable of routing data from up to four PDM microphones to the local I²S port for beam-forming or other local data processing.  Further enhancements to the AD242x allow for concurrently receiving up to four PDM mic inputs plus an additional I²S audio stream.    

The AD2426W, AD2427W and AD2428W are compliant with all relevant automotive EMC, EMI and ESD requirements, are fully AEC-Q100 qualified, and operate over the extended automotive temperature range (-40 to 105℃).

They are released to production and are available now in a 32-lead LFCSP (5.0 x 5.0mm) package and supported within the company’s SigmaStudio graphical development environment and ecosystem of third party development, prototyping, and evaluation solutions.
