Application Scheme
The TDA7500A can operate as a standalone device either it can interface the TDA7501 which contains
the analog input multiplexer, analog volume control and the line-driver. The FM_MPX and FM_LEVEL sig-
nals coming from the tuner and other signals supplied by analog sources are adapted by the TDA7501
and fed to the TDA7500A. A block diagram of the system is shown in Fig. 20 below.
The TDA7500A converts all the analog signals into digital domain and performs AM/FM processing and
audio/sound processing. Thanks to this, it is possible to process any audio source as well analog as digital
in parallel, to record FM mono for traffic information, telephone response, navigation 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 control.
