Analog ANC solution
Active Noise Cancellation technology maximizes the end-user experience in today's advanced world of mobile communications, enabling crystal clear sound during phone conversations or music listening regardless of the surrounding environment noise.
A highly integrated system in combination with lowest power consumption on the market plus a cost-effective price model makes the AS3412 ideally suited for smartphones or other mobile devices.
The AS3412 is targeting feed-forward topology and is able to effectively reduce ambient noise up to 3 kHz. Used in a true wireless ear piece AS3412 even enables state of the art hybrid noise cancellation.
This product suits for the following applications:
- Mobile accessory
- Stereo on-ear headsets
- Stereo earpieces
- Multimedia devices

AS3418 - Active Noise Cancellation
The AS3418 is ideally suited to enable ANC for true wireless earbuds due to its smallest size, lowest power consumption and best-in-class ANC. It improves the quality of music listening or phone conversations by reducing background ambient noise (>30dB). Because of its small system footprint, manufacturers are empowered to build ANC in very small and aesthetic form factors.
