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
● All functions programmable via serial I2 C 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
