ADC34J23: ADC34J23 Dynamic Range.

What is the FFT point?

This chart is measured at -1 dBFS. This will set the noise floor at approximately -96dBFs (if using dither enabled with 10MHz input signal).

I'm asking about the FFT point at the time of measurement.

We don't have the number of FFT bins listed for these measurements unfortunately so I cannot comment on the RBW or the bin number. The sample rate is at 80MSPS for all of these specifications above.
