Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

带MIC/视频开关的自动插孔发送/结束检测

说明

特性

FSA8009是一款音频插孔麦克风/视频开关，用于具有发送/结

束(S/E)检测的3或4极附件。除了检测外，FSA8029还包含集成

式麦克风/视频开关，允许处理器配置音频插孔。该架构的设

计旨在允许常见的第三方耳机用于从手机、个人媒体播放器和

便携式外围设备听音乐。
