APPLICATION DIAGRAM

Hereafter are some examples of Applications in which the TDA7580 can be used. They are just basic references

as the device can operate.

Figure 12. 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 13. 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.
