Description

The TDA7303 is a volume, tone (bass and treble) balance (Left/Right) and fader (front/rear) processor for quality audio applications in car radio, Hi-Fi and portable systems.

Selectable input gain and external loudness function are provided. Control is accomplished by serial I²C bus microprocessor interface.

The TDA7303 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 Low DC stepping are obtained.
