DESCRIPTIONThe 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
and switches combined with operational amplifiers.
Thanks to the used BIPOLAR/CMOS Tecnology,
Low Distortion, Low Noise and DC stepping are ob-
tained.

Note:(1) Bass and Treble response see attached diagram (fig.19). The center frequency and quality of the resonance behaviour can be choosen by
the external circuitry. A standard first order bass response can be realized by a standard feedback network.
