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.

Features

■ 6pF Typical Switch Off Capacitance for HS USB

■ 2.5Ω Typical On Resistance for Audio Signaling

■ Flow-Through Pin Out Eliminates PCB Vias

■ Built-In Termination on Unselected Audio Paths Inhibits Audio Pop

Applications

■ Cell Phone, PDA, Digital Camera, and Notebook

■ LCD Monitor, TV, and Set-Top Box
