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.

FSA8029
Audio Jack Send / End Detection with MIC / Video Switch
Description
Features
The FSA8029 is an audio jack microphone / video switch for
3- or 4-pole accessories with send / end (S/E) detection. In
addition to detection, the FSA8029 features an integrated
microphone / video switch that allows the processor to
configure the audio jack. The architecture is designed to
allow common third-party headphones to be used for
listening to music from mobile handsets, personal media
players, and portable peripheral devices.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable
above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition,
extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute
maximum ratings are stress ratings only.
