DESCRIPTION

The TDA7443D is a volume tone (bass and treble)

balance (Left/Right) processor for quality audio appli-

cations 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 ampli-

fiers.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are ob-

tained.
