TDA7433
DESCRIPTION
The TDA7433 is a volume, tone (bass and treble) balance (Left/Right) processor for quality audio applications in car radio and Hi-Fi systems. Control is acplished by serial bus microprocessor interface. The AC signal setting is obtained by resistor networks and switches bined with operational amplifiers. BLOCK DIAGRAM
