Determination of the ENOB in 56F8367

The effective number of bits (ENOB) in the 56F8367 chip is listed at 9.6 bits.

Now, I know that this number is determined by testing and the frequency of the input signal (and sampling rate) both have an affect on the ENOB calculation.

I am working on a fundamental frequency of only 60Hz. I am relatively new to DPS but I know that this frequency is very low. So I was wondering how much, if at all, I can consider my frequency "DC" for this chip or how much such a low frequency will have an effect on the ENOB.

If the test was performed on frequency in the kHz range, I can't imagine that I would be getting a higher ENOB than 9.6.

So does anyone know what test conditions they used to calculated or measure this number?
