Dialog introduces a family of audio codecs with groundbreaking active noise reduction performance

     Dialog Semiconductor, a supplier of highly integrated power management, audio, AC/DC power conversion, charging, and Bluetooth low power technologies, announced the introduction of the DA740x, a highly integrated audio codec chip with the industry's best active noise cancellation (ANC) performance, providing the fastest audio performance in the rapidly growing wireless headphone market regardless of any environment.

     The global wireless headphone market is expected to grow at a compound annual growth rate of 20%, generating approximately $34 billion in revenue by 2024. With active noise reduction fast becoming the de facto standard, Dialog is poised to capture a significant market share with the DA740x product family.

     The DA740x series supports feedforward and feedback active noise cancellation topologies, where noise cancellation microphones are located outside or inside the headphone cavity. With its integrated custom filtering capabilities, the DA740x also supports full hybrid mode, combining the best of both worlds to deliver high performance active noise reduction with the best audio quality and the longest battery life. The chip family is independent of the audio interface type, which means it can be used in both wired and wireless applications.

     The DA740x's digital implementation and software-based complementary tuning tools help Dialog customers achieve proactive noise reduction designs with fewer external components and faster time-to-market compared to typical analog-based designs. Analog based designs require a lot of analog circuits and element level tuning.

     Sean McGrath, senior vice president and general manager of the Connectivity and Audio Technologies Business Unit at Dialog Semiconductors, said: "This groundbreaking new audio codec family is expected to significantly increase Dialog's share of the growing wireless headset market. The highly integrated design approach provides our customers with superior active noise cancellation performance and audio quality, while using fewer external components and occupying a board size of less than 6 mm2, making it equally suitable for the smallest in-ear headphones. The DA740x helps manufacturers create higher quality, lower power products in a smaller size, while accelerating their time to market."
