Signal-sources switch |
TDA1029 |
|
|
|
|
The TDA1029 is a dual operational amplifier (connected as an impedance converter) each amplifier having 4 mutually switchable inputs which are protected by clamping diodes. 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.

In the case of offset control, an internal blocking circuit of the switch control ensures that not more than one input will be switched on at a time. In that case safe switching-through is obtained at VSL ≤ 1,5 V.
