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 accomplished by serial bus microproc-
essor interface.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers.
Thanks to the advanced BIPOLAR/CMOS Tech-
nology, the external components have been re-
duced.
