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 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.
