DESCRIPTION
The TDA7434 is a volume, tone (bass and treble)
balance (Left/ Right) fader (Front / Rear) proces-
sor for quality audio applications in car radio and
Hi-Fi systems.
Control is accomplished by serial bus microproc-
essor interface.

SDIP24
ORDERING NUMBER: TDA7434
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.
