DESCRIPTION

The TDA7430/7431 are volume tone (bass middle and treble) balance (Left/Right) processors with voice canceller for quality audio applications in car radio and Hi-Fi systems. They reproduce surround sound by using pro- grammable phase shifters and a signal matrix. Control of all the functions is accomplished by se- rial bus. The AC signal setting is obtained by resistor net- works and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
