TDA7313

® TDA7313 DIGITAL CONTROLLED STEREO AUDIO PROCESSOR WITH LOUDNESS 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 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 PIN CONNECTION (Top view) DIP28 SO28 ORDERING NUMBERS: TDA7313 TDA7313D 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 andswitches combined with operationalamplifiers. Thanks to the used BIPOLAR/CMOS Tecnology, Low Distortion, Low Noise and Low DC stepping are obtained.
