Overview
® TDA7311 SERIAL BUS CONTROLLED AUDIO PROCESSOR INPUT MULTIPLEXER – TWO STEREO DIFFERENTIAL INPUTS – TWO STEREO SINGLE ENDED INPUTS – ONE MONO DIFFERENTIAL INPUT INPUT AND OUTPUT FOR EXTERNAL EQUALIZER OR NOISE REDUCTION SYSTEM 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 SPI COMPATIBLE SERIAL BUS DESCRIPTION The TDA7311 is a volume, tone (bass and treble) and fader (front/rear) processor for high quality audio applications in car radio and Hi-Fi systems.
PINS CONNECTION (Top view) DIP40 ORDERING NUMBER: TDA7311 Control is accomplished by serial 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 DC stepping are obtained.
