综述

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.

本产品适用于以下应用:

  • TrueWireless ANC earbuds
  • Mono Earpieces
  • Stereo Earpieces
  • USB-C Headsets
  • MFi Headsets
