General Description
Analog ANC solution
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.
This product suits for the following applications:
- TrueWireless ANC earbuds
- Mono Earpieces
- Stereo Earpieces
- USB-C Headsets
- MFi Headsets
