Fairchild Semiconductor's FSA8049 complies with the Open Mobile Terminal Platform (OMTP) and Cellular Telephone Industries Association (CTIA) audio configuration jack standards.

The device detects the locations of the ground (GND) and microphone (MIC) poles on the audio plug and automatically routes them to the appropriate connections. This allows the end-user to plug accessories, such as headsets, with different audio pole configurations into the device and have them operate correctly.


  • Ability to detect two different audio jack configurations and connect properly to each standard, enables use of all existing headsets in new devices without manual configuration
  • Automatically routes GND and MIC to audio jack terminals
  • Ability to detect 3- or 4- pole audio accessories
  • Small foot print, 9-ball WLCSP 3x3 array saves board space
  • Suitable for use in cellular phones, smart phones, tablets and laptop computers
