Testing out a new (Mouser) ADAU1701miniz eval board and have a concern about high THD. THD exceeds 0.2% at high audio frequencies at input levels 3dB below full scale. See attached. Configuration is a straight stereo in-out. no processing. Have disabled the on-board class d amp, reset, etc....  My 1761 eval is 10dB better and a "MINI-DSP" version of the 1701 is 15dB better. Do I have a bad unit or ??????
