DESCRIPTION

The TDA7314 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 and internal loudness function

are provided. Control is accomplished by serial 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 DC stepping are ob-

tained.
