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.
