Audio Jack Send / End Detection with MIC / Video Switch

Description

Features

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.
