Description
The FSA221 is a Double-Pole, Double Throw (DPDT)
multiplexer that combines a low-distortion audio and a
USB2.0
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 portable peripheral devices.
Since USB2.0 is an industry standard for shared data-
path in portable devices, the FSA221 also incorporates
a V
power-off feature to minimize current consumption when
V
for the common D+/R, D-/L ports only. Typical
applications
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.
