This stereo audio switch circuit allows that with only one switch to select one of the four stereo channels. The internal switching is made posible with CMOS components.
Each switch input includes a voltage divider to allow the switch to work in the linear zone of the characteristics, this ensures low audio signal distorsions.
Through the stereo switch circuit will flow a 1 mA current intensity at 5V. This voltage can be increased up to 15V.
