I have an adau 1702. The audio signal comes from the analog input and it will convert to the i2s.
The analog input is filtered as the mini evalboard from analog device.
but the problem is that the analog signal is noise over the hole frequencyband width. the noise wont be louder if i set up the analog signal higher. its always the the same. the adau is configured with the sigma software.
has anyone an idea whats the problem?
thank you very much,
