Using an Audio Precision analyzer with 22-22K filter, I measure the EVM headphone output noise at about -75 dBu and peak audio output of roughly +8dBu. The datasheet spec for SNR of headphone amp is 101/105 dB. I am hearing white noise that seems to be 10-20 dB higher than I would expect if SNR is truly 100dB. See about the same results on EVM as on our hardware design. How is TI coming up with the 100 dB SNR?
