Description
The FSA2000 is a low-cost integrated HS-USB and audio
switch that incorporates an audio headphone amplifier. This
solution eliminates many of the discrete parts currently used
in stereo headset applications. It provides stereo headphone
drivers designed to operate with a ground-centered output
signal. This allows for the removal of large and expensive
DC blocking capacitors. The headphone drivers are capable
of driving up to 40mWRMS per channel.
