1 / 15 page 1/15 TDA7443D July 2002 This is preliminary information on a new product now in development. Details are subject to change without notice. s INPUT MULTIPLEXER - 5 STEREO INPUTS - SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTATION TO DIFFERENT SOURCES s ONE STEREO OUTPUT s AGC s TREBLE AND BASS CONTROL IN 2.0dB STEPS s VOLUME CONTROL IN 1.0dB STEPS s TWO SPEAKER ATTENUATORS: - TWO INDEPENDENT SPEAKER CONTROL IN 1.0dB STEPS FOR BALANCE FACILITY - INDEPENDENT MUTE FUNCTION s TWO SURROND MODES AVAILABLE - MUSIC PSEUDO STEREO s ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The TDA7443D is a volume tone (bass and treble) balance (Left/Right) processor for quality audio appli- cations in Hi-Fi systems. Selectable input gain is provided. Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor net- works and switches combined with operational ampli- fiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are ob- tained.
