Overview
TDA7409 CARRADIO-SIGNAL-PROCESSOR s s s s s s s 4 STEREO INPUTSSOFTSTEP-VOLUME BASS, TREBLE AND LOUDNESS CONTROL DIRECT MUTE AND SOFTMUTE INTERNAL BEEP FOUR INDEPENDENT SPEAKER-OUTPUTS SUBWOOFER STEREO OUTPUT DIGITAL CONTROL: 2 q I C-BUS INTERFACE q AUDIO-FILTER CHARACTERISTICS PROGRAMMABLE SO20 ORDERING NUMBER: TDA7409D DESCRIPTION The TDA7409 is a high performance signal processor specificall designed for car radio applications.
The device includes a high performance audioprocessor with fully integrated audio filters.
The digital control allows a programming in a wide range of all the filter characteristics.
By the use of a BICMOSBLOCK DIAGRAM process and a linear signal processing low distortion and low noise are obtained.
