When calculating an ADC or DAC ENOB, do you use SNDR or SINAD, SFDR, SNR or SDR or something else ?
I have see all used in calculating the ENOB, so which one is correct ?

I use SINAD to calculate ENOB.
\begin{equation} \text{ENOB} = \frac{\text{SINAD[dB]}-1.76}{6.02} \end{equation}
The wikipedia agrees as an often used definition for ENOB : Effective number of bits
