DESCRIPTION

The TDA7312 is a volume, tone (bass and treble)

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

cations.

Control is accomplished by serial I

essor interface.

The AC signal setting is obtained by resistor networks

andswitches combined with operationalamplifiers.

Thanks to the used BIPOLAR/CMOS Tecnology,

Low Distortion, Low Noise and Low DC stepping are

obtained.
