TLV320AIC3104 Routing the ADC to the digital Effects

At which Register I can route the ADC Input to the digital effects?

In the block diagramm I see SW-D1 and SW-D3.

But I didn't find the register to route the signal in this way !

Up to now I choose the digital output of the TLV320 and connect it to the digital Input by hardware.

But for product i can't do in this way, becausein this case I need additional MUX and I haven't the space for it.

(The Application is very cost and space sensitive).

Much thanks for your help .....

Hi Richard,

Please check out the "DIGITAL AUDIO PROCESSING FOR RECORD PATH" section of the datasheet starting on page 28 of the datasheet.

Best Regards,

Hi Dave

This means, I can't use the digital effects and Volume control with ADC in ???I need this, because I have to use analog in with digital processing and Volume control.

I made earlier tests:

When I route the ADC to Dout and routed it hardware wise(Jumper) back to Din --> Effets --> Volume --> DAC it seems that it was working well.
Is this correct ?

Much thanks for your answers and best regards,
Richard

Yes, this has to be looped back externally.
