TDA7313N

® TDA7313N DIGITAL CONTROLLED STEREO AUDIO PROCESSOR WITH LOUDNESS INPUT MULTIPLEXER: - 3 STEREO INPUTS - SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTION TO DIFFERENT SOURCES 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 TDA7313N 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 DIP28 SO28 ORDERING NUMBERS: TDA7313N TDA7313ND are provided. Control is accomplished by serial I2C busmicroprocessor 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.
