FSA201 — USB2.0 Full-Speed and Audio

Switches with Negative Signal Capability

Features

Description

The FSA201 is a Double-Pole, Double Throw (DPDT)

multiplexer that combines a low-distortion audio and a

USB2.0 Full-Speed (FS) switch path. This configuration

enables audio and USB data to share a common

connector port. The architecture is designed to allow

audio signals to swing below ground. This means a common

USB and headphone jack can be used for personal media

players and similar portable peripheral devices.

3Ω Typical ON Resistance

-3db Bandwidth: > 250MHz

Low Power Consumption

Packaged in Pb-free 10-pin MSOP and

10-Lead MicroPak™ (1.6 x 2.1mm)

Power-off Protection on Common D+/R, D-/L Ports

Since USB2.0 is an industry standard for shared data-

path in portable devices, the FSA201 also incorporates

a V_BUSdetection capability. The FSA201 includes a

power-off feature to minimize current consumption when

V_BUSis not present. This power-off circuitry is available

for the common D+/R, D-/L ports only. Typical

applications involve switching in portables and

consumer applications, such as cell phones, digital

cameras, and notebooks with hubs or controllers.
