ORDERING NUMBERS: TDA7430 (TQFP44) TDA7431 (SDIP42) 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 acplished by serial bus. The AC signal setting is obtained by resistor networks and switches bined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
