1 / 22 page 1/22 TDA7429 June 2004 1FEATURES ■ 3 STEREO INPUTS ■ INPUT ATTENUATION CONTROL IN 0.5dB STEP ■ TREBLE MIDDLE AND BASS CONTROL ■ THREE SURROUND MODES ARE AVAILABLE – MUSIC: 4 SELECTABLE RESPONSES – MOVIE AND SIMULATED: 256 SELECTABLE RESPONSES ■ FOUR SPEAKERS ATTENUATORS: – 4 INDEPENDENT SPEAKERS CONTROL IN 1dB STEPS FOR BALANCE FACILITY – INDEPENDENT MUTE FUNCTION ■ ALL FUNCTIONS PROGRAMMABLE VIA SERIAL BUS 2 DESCRIPTION The TDA7429 is volume tone (bass middle and tre- ble) balance (Left/Right) processors for quality audio applications in TV and Hi-Fi systems. It reproduces surround sound by using programma- ble phase shifters and a signal matrix. 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 obtained. DIGITALLY CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX Figure 2.
