DESCRIPTION
The TDA7467 is a SRS (Sound Retrieval System)
audio matrix. It reproduces SRS sound process-
ing stereo and mono sources both.
The SRS sound is guaranteed by external com-
ponents and it is not affected by internal process
spreads.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers according to the SRS labs specifica-

tion.
Control of all the functions is accomplished by serial
bus. Thanks to the used BIPOLAR/CMOS/DMOS
technology, Low Distortion, Low Noise and DC
stepping are obtained.
