DESCRIPTION

The TDA7318 is a volume, tone (bass and treble)

balance (Left/Right) and fader (front/rear) processor

for quality audio applications in car radio and Hi-Fi

systems.

Selectable input gain is provided. Control is accom-

plished by serial I

2C bus microprocessor 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.
