Product overview

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 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.
  • All features

    • All functions programmable via serial I2C bus
    • Input multiplexer:3 stereo inputsSelectable input gain for optimal adaptation to different sources
    • Loudness function
    • Volume control in 1.25 dB steps
    • Four speaker attenuators:4 independent speakers control in 1.25d B steps for balance and fader facilitiesIndependent mute function
    • Treble and bass controL
