Audio Switch with Negative Signal Capability
Features
3:1 Switch Handles:
- Audio Headsets
- UART
- High- and Low-Speed USB Data
USB Charger Detection and Indication
Negative-Swing-Capable Audio Channel
Built-in Termination Resistors for Audio Pop

Description
The FSA800 is a 3:1 USB accessory switch that
enables USB data, stereo and mono audio,
microphone, and UART data to share a common
connector port. It is designed for high-speed USB 2.0
signaling. The architecture is designed to allow audio
signals to swing below ground so a common USB and
headphone jack can be used for personal media
players and portable peripheral devices.
FSA800 detects wall chargers through a dedicated pin
that provides the baseband with charger detection.
The FSA800 meets both USB Rev. 2.0 and micro-USB
specifications.
Applications
Cell Phones, MP3 Players, PDAs
