Full Scale is relative to the magnitude of VCCA and can be calculated as FS = VCCA/3.3.
Distortion is measured in the standard way as the combined quantity of distortion products plus noise. The signal
level for distortion measurements is at 3dB below full scale, unless otherwise noted.
SNR measured with a -100dbFS signal at input.
