FSA110 Datasheet Audio and Wired-OR USB2.0 Hi-Speed(480Mbps) Switch

Manufacturer: Fairchild (now onsemi)

General Description

The FSA110 is a Double-Pole, Single Throw (DPST) switch that combines a low-distortion audio path with low off capacitance for USB applications.

This configuration is ideal for wired-OR configurations, enabling shared USB2.0 Hi-Speed (HS) and audio on a single connector.

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.
