DESCRIPTION
The TDA7463AD is a volume tone (bass and tre-
ble) 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.
