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
microprocessorinterface.
The AC signal setting is obtained by resistor networks
andswitches combinedwith operationalamplifiers.
Thanks to the used BIPOLAR/CMOS Tecnology,
Low Distortion, Low Noise and DC stepping are ob-
tained.
