DESCRIPTION
The TDA7464 is a volume tone (bass middle and
treble)balance (Left/Right) processorswith stereo
SRS and voicecanceller for quality audio applica-
tionsin car radio, Hi-Fi, TV systems.
It reproduces SRS (Sound Retrieval System)
sound by external components and surround
sound by using phase shifters and a signal ma-
trix. The AC signal setting is obtained by resistor
networks and switches combined with operational
amplifiers according to the SRS laboratories
specification. Control of all the functions is ac-
complishedby serial bus.
Thanks to the used BIPOLAR/CMOSTechnology,
Low Distortion, Low Noise and DC stepping are
obtained.
