PCM1802: Dynamic range vs SNR

Part Number: PCM1802

Hi Team,

We find that Dynamic Range of PCM1802 is larger than its SNR, according to my understanding, when doing Dynamic Range, the input should have -60dB input, that means Dynamic Range is usually smaller than SNR. So could you share the measurement about this 2 spec? and the root cause why Dynamic Range is larger than SNR? Great thanks.

Best Regards.

Hi Wiky,

I'll have to look into this bit more to gather the char data for these plots in DS. Updates to follow. Thanks.

Best regards,
Ravi

Hi Ravi,

could you help us find the root cause? it looks very strange and we are curious about it, great thanks.
