TDA7314

® TDA7314 DIGITAL CONTROLLED AUDIO PROCESSOR WITH LOUDNESS 1 STEREO INPUT 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 BUS DESCRIPTION The TDA7314 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. PIN CONNECTION (Top view) SDIP24 ORDERING NUMBER: TDA7314 Selectable input gain and internal loudness function are provided. Control is accomplished by serial 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 DC stepping are obtained.
