    | Partname: | TDA7431 |  
    | Description: | DIGITALLY CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX AND VOICE CANCELLER |     
    | Manufacturer: | SGS-Thomson Microelectronics |  
    | Datasheet: | PDF (168K). Click here to download *) |  
    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.  |
