PCM1794A left/right channel distortion difference

Right channel is constantly weaker but the results are very consistent between measurements, parts, and even different opamp models, while left channel shows better performance but the results are very inconsistent. I will show few examples from different measurements. To be honest, I still do not know what … Continue reading
