Dialog Semiconductor announced the DA740x, a family of highly-integrated audio codec chips that deliver best-in-class active noise cancellation (ANC), providing optimal audio performance in any environment to the rapidly-growing wireless headphones market.
The DA740x supports feedforward and feedback ANC topologies, in which the noise cancelling microphones are located either outside or inside the headphone cup. With its integrated custom filtering, the DA740x also enables a fully hybrid implementation which combines the best of both worlds by providing high performance ANC while maximizing audio quality and battery life. The chip family is agnostic to the type of audio interface meaning it is effective in both wired and wireless applications.
DA740x’s digital implementation and complementary software-based tuning tools enable Dialog customers to realize their ANC designs with far fewer external components and faster time-to-market compared to typical analog-based designs, which require significant analog circuitry and component-level tuning (more info).
