The maximum S/N ratio for 14-bit converter is 86 dB, therefore 75 dB sounds realistic. > However, this value comprises for the > whole bandwidth of 32MHz.

This is certainly true ON AVERAGE, but may fail in individual cases, depending on the nature of the quantization noise. 73, Sinisa YT1NT, VE3EA
