Digital Controlled Audio Processor 28-Pin SO T/R

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.

Input multiplexer: 3 stereo inputs Selectable input gain for optimal adaptation to different sources

Volume control in 1.25 dB steps

Loudness function

Treble and bass controL

Four speaker attenuators: 4 independent speakers control in 1.25d B steps for balance and fader facilities Independent mute function

All functions programmable via serial I²C bus
