TDA7430/TDA7431 is a 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 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 resis- tor networks and switches combined with operational amplifiers. Thanks to the used BIPO- LAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
The document describes the TDA7430 and TDA7431, which are volume, tone (bass, middle, treble), balance, and voice canceller processors designed for quality audio applications in car radio and Hi-Fi systems. These devices reproduce surround sound using programmable phase shifters and a signal matrix.
