Ordering Information
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.
 Determines When Send / End Button Key is Pressed
 Integrates a MIC / Video Switch for 4-Pole Configuration
 Reduces Pop / Click Caused by Microphone Bias

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.
