I need calculate noise level for whole system, but I have a question about how to calculate PCM1862's output noise level:
PCM1862 has 103dB SNR in Differential Ended input mode,and the 0dBFS input level is 4.2Vrms, so the noise level maybe ~30uV, right?
PCM1862 has 103dB SNR in Single Ended input mode,and the 0dBFS input level is 2.1Vrms, so the noise level maybe 15uV;
Question is: noise level is even higher in Differential Ended input mode?
Thanks!
Harley
