DESCRIPTION

The TDA7430/TDA7431 is volume tone (bass middle and treble) balance (Left/Right) processors voice canceller for quality audio applications in car radio and Hi-Fi systems.

They reproduce surround sound by using programmable phase shifters and a signal matrix.

Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are obtained.
