2DESCRIPTION

The TDA7468D is a volume tone (bass and treble)

balance (Left/Right) processor for quality audio

applications in Hi-Fi systems.

Selectable input gain is provided. 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
