ADC's and DAC's for audio

[Eeyore]

The datasheet is written for those knowledgeable in A/D specification.
It is understood that S/N refers to the maximum obtainable and this
obviously occurs at full scale input signal levels- where else.

Utter rubbish, certainly in audio.

SNR refers to an established ( standard usually ) reference level.

Systems invariably have additional headroom, so the dynamic range exceeds SNR by
the headroom available.

Not only are you an offensive oafs, Bloggs but you talk total crap too !

You continue to exemplify my assertions about your lack of your worth.
You know nothing beyond abbreviated manufacturers' blurbs and hype. The
performance definitions are fundamental regardless of the marketing
dementia. It is clear you have never understood anything in your entire
life.

It's clear that you know nothing about audio standards. Try visiting aes.org

Fred is completely correct in the case of an ADC datasheet, even if the
ADC is designed for audio use. When no reference is given, SNR on an
ADC datasheet is always assumed to be referenced to full scale.

It was very clear from the context that this wasn't the case here though. The specs
referred to a microphone.
