I am working on ADAU1777. I would want to know if there is any way to create a sine waveform generator by connecting the DAC output to unused ADC input.
So you mean to feedback a signal from the DAC back to the ADC to setup an oscillation and then be able to control it? I cannot say that I have tried this! It seems like this would be somewhat unstable and difficult to ensure that it would work with every unit. But, I suppose it could be done but I don't think this will work well.
Let us know if you are able to do it. I just know that in the old analog days getting something to oscillate reliably can be difficult.
Why not just use an ADAU1701?
