Description

The TDA7313 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 external loudness function are provided. Control is accomplished by serial I ² C busmicro -processor interface.

TheAC signal setting of the TDA7313 is obtained by resistor networks andswitches combinedwith operationalamplifiers.

Thanks to the used BIPOLAR/CMOS Tecnology, LowDistortion, Low Noise and Low DC stepping are obtained.
