TDA7432 Datasheet - STMicroelectronics

DESCRIPTION
The TDA7432 is a volume, tone (bass and treble) balance (Left/Right) processor for quality audio
applications in car radio and Hi-Fi systems. Control is accomplished by serial bus microprocessor interface. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.
Thanks to the advanced BIPOLAR/CMOS Tech nology, the external components have been reduced.
