Product Summary

The TDA7313ND 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 I2C busmicroprocessor interface. The AC signal setting of the TDA7313ND is obtained by resistor networks andswitches combinedwith operationalamplifiers. Thanks to the used BIPOLAR/CMOS Tecnology, LowDistortion, Low Noise and Low DC stepping are obtained.
