Hello. I am designing a system for audio processing.
The problem is I am not good at analog electronics. The manual of the IC I am using, is saying that:
"The ADC full-scale range is 1.0 VRMS at AVDD = 3.3 V. The full-scale range tracks linearly with analog supply voltage AVDD. To avoid distortions, it is important not to exceed the full-scale range."
I am totally lost here. What does it mean? 1 Vrms = squareroot(2)/2? So my maximum voltage must be 0.354 Volt? And after the ADC, again, the maximum voltage I am going to use in order to convert my integer values into floating point numbers, will be 0.354 again?
Thanks for any help.
