TDA7303 audio processor with loudness

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 AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.

Thanks to the used bipolar/CMOS technology, low distortion, low noise and low DC stepping are obtained.
