Description
The FSA8009 is an audio jack microphone / video switch for
3- or 4-pole accessories with send / end (S/E) detection. In
addition to detection, the FSA8009 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.
