TDA7500

DIGITAL AM/FM SIGNAL PROCESSOR

STMicroelectronics 

TDA7500

digital domain and performs AM/FM processing

and audio/sound processing. Thanks to this, it is

possible to process any audio source as well ana-

log as digital in parallel, to record FM mono for

traffic information, telephone response, naviga-

tion and RDS. Finally the digital signals are D/A

converted and sent to the TDA7501 for the final

level adjustment and for the analog volume con-

trol.
