2 DESCRIPTION
The TDA7463 is a volume tone (bass and treble)
processor for quality audio applications in Low
voltage supply portable systems.
Bass ALC (Automatic Level Control) function can
be adjusted by a dedicated pin. The control of all

the functions is accomplished by serial bus.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers. Thanks to the used BIPOLAR/CMOS
Technology,
Low Distortion, Low Noise and DC stepping are
obtained.obtained.
