ADI Adds Improved Automotive Audio Bus A2B Transceiver Products
Published2017.02.28 10:30Stands Out in Automotive Communication and Active Noise Cancellation
Analog Devices (ADI) has launched three automotive audio bus (A2B) transceiver products with enhanced performance. According to ADI, the newly released products are used to distribute audio and control data, clock, and power over a single UTP (unshielded twisted-pair) cable. The AD242x family of A2B transceivers provides versatile slave-to-slave communication capabilities and supports low-speed sampling modes. Both of these features significantly improve overall bus bandwidth utilization and make a significant difference in emerging automotive communication and active noise cancellation applications.
All newly released AD242x family products incorporate an enhanced pulse density modulation (PDM) block. The AD242x family provides improved GPIO, I2C, and clocking performance, further enhancing system-level applicability. By extending A2B technology to premium systems, the AD242x family can support daisy-chain configurations with a maximum of 11 nodes, with inter-node distances of up to 15m. The AD2425, AD2422, and AD2421 comply with all automotive-related EMC, EMI, and ESD requirements and have obtained AEC-Q100 certification. Additionally, these products operate across an extended automotive temperature range (-40°C to +105°C).

A single misaligned light means 'defect'… Vehicle interior lighting now guarded by semiconductors and software
Automotive interior lighting is moving beyond its role as 'auxiliary lighting.' As it becomes a core element of user experience (UX) that expresses brand identity through color and animation while reflecting driver preferences, the LED interior ambient lighting market is growing rapidly. In connection with this, we met in advance with Choi Young-jae, Research Director at Dabo Corporation, who will present a technical webinar session on "Intelligent LED Interior Lighting Solutions Illuminating Future Vehicles," to hear about market trends and changes in design requirements.

TI Unveils Multi-Axis Coreless Current Sensor TMCS2100-Q1 for HEV/EV Traction Inverters
Texas Instruments has unveiled the TMCS2100-Q1, a multi-axis coreless Hall-effect current sensor for HEV and EV traction inverters. By simultaneously measuring horizontal and vertical magnetic fields through multi-axis sensing technology, it achieves up to 20 times higher accuracy compared to conventional single-axis sensors, while the busbar-unmodified design provides mechanical design flexibility. It simultaneously meets the high-accuracy requirements and miniaturization driven by the expansion of 800V architectures.
