TDA7535
Dual 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.

External Audio Receiver
with its owned audio rate Fs
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.
