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.

Key Features
