2DESCRIPTIONThe TDA7469 is a volume tone (bass and treble) pro-
cessor 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 ampli-
fiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are ob-
tained.
