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 40mW
