- Qualified for automotive applications
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 AD2402 is a feature and cost reduced member of the A2B family specifically targeting connectivity to PDM-output microphones and sensors.
The AD2402 is targeted for use in wiring intensive applications where reducing the weight or complexity of existing cable harnesses is a primary system design objective. In the automotive segment, this weight reduction leads to significant improvements in fuel efficiency which is particularly important as car manufacturers are forced to comply with increasingly more stringent government standards.
Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
