Application diagrams
Figure 17. Radio mode with external slave audio DAC
In this mode an external slave stereo DAC, like the ST TDA7535, can be easily connected
and the TDA7580 outputs the audio from radio station at 36kHz rate.
Figure 18. Radio mode with external master audio device
An external digital audio device is connected externally as a digital audio master, and the
internal TDA7580 sample rate converter is responsible for the conversion from internal
36kHz to the external audio rate.
