Introduction

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.

Features

• 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 1.25 dB steps for balance and fader facilities
• Independent mute function
• All functions programmable via serial I²C bus

Applications

• car radio
• Hi-Fi
• portable systems
