TDA1029 Signal-sources switch

This signal source switch electronic project is based on the TDA1029 IC .
The TDA1029 signal source switchis a dual operational amplifier (connected as an impedance converter) each amplifier having 4 mutually switchable inputs which are protected by clamping diodes. Signal-sources switch can be made in various mods :

With an electronic specialized circuit like tda1029.
Mechanical, with a mechanic switch
With an electronic or electric circuit ( with relays).
The input currents are independent of switch position and the outputs are short-circuit protected.
The device is intended as an electronic two-channel signal-source switch in a.f. amplifiers.
