Fairchild Semiconductor FSA2000 HS-USB Switch
with Audio Amplifier
The Fairchild Semiconductor FSA2000 HS-USB and audio switch incorporates a cap-free audio headphone amplifier and eliminates many of the discrete parts currently used in stereo headset applications. The Fairchild Semiconductor FSA2000 HS-USB switch with Class AB audio amplifier 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 of the FSA2000 are capable of driving up to 40WRMS per channel. This Fairchild Semiconductor HS-USB switch is designed for use in MP3 player, cell phone, and smart phone applications.
