Dialog Semiconductor DA740x family of highly-integrated audio codec chips are said to deliver best-in-class active noise cancellation (ANC), providing optimal audio performance in any environment. The devices target the wireless headphones market, which is forecast to grow at a CAGR of 20%, generating revenues of around $34 billion by 2024.
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. The chip family is agnostic to the type of audio interface meaning it is effective in both wired and wireless applications.
The family consists of three chips:
- DA7402: stereo high performance (HP) codec with ANC
- DA7401: mono HP codec with ANC
- DA7400: stereo HP codec.
