This configuration allows the system designer to use a common connector for audio and USB data. The audio switch is designed to allow audio signals to swing below ground which makes this common connector configuration possible. The TS5USBA224 is powered up using VAUDIO. When ASEL=High, the audio path is selected regardless of the logic level at VBUS. If ASEL...
