TDA7303 Datasheet PDF - ST Microelectronics

●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
