Other Parts Discussed in Thread: PCM5102A, PCM5101A,
A customer measured audio performance of PCM5102EVM-U. The SNR was 106dB, so he made a complaint about it. Because it is worse 6dB than typical value of the PCM5102A specification, same as PCM5101A specification.
I also measured the SNR of another PCM5102EVM-U using the System Two Cascade by Audio Precision. The SNR without A-weight filter was 106dB, because both filters cannot be enabled at the same time on System Two Cascade. However, the SNR of PCM5102A specification is A-weighted value. Is the difference of 6dB caused by A-weight filter?
