DESCRIPTION
The TDA7313 is a volume, tone (bass and treble) balance (Left/Right) and fader (front/rear) processor for quality audio applications in car radio and Hi-Fi systems.
Selectable input gain and external loudness function are provided. Control is accomplished by serial I2C busmicroprocessor interface.
TheAC signalsettingis obtainedby resistor networks andswitches combinedwith operationalamplifiers. Thanks to the used BIPOLAR/CMOS Tecnology,
Low Distortion, Low Noise and Low DC stepping are obtained.

■ INPUT MULTIPLEXER:
    - 3 STEREO INPUTS
    - SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTION TO DIFFERENT SOURCES
■ INPUT AND OUTPUT FOR EXTERNAL EQUALIZER OR NOISE REDUCTION SYSTEM
■ LOUDNESS FUNCTION
■ VOLUME CONTROL IN 1.25dB STEPS
■ TREBLE AND BASS CONTROL
■ FOUR SPEAKER ATTENUATORS:
    - 4 INDEPENDENT SPEAKERS CONTROL IN 1.25dB STEPS FOR BALANCE AND FADER FACILITIES
    - INDEPENDENT MUTE FUNCTION
■ ALL FUNCTIONS PROGRAMMABLE VIA SERIAL I2C BUS
