All Min/Max limits are guaranteed by Winbond via electrical testing or characterization. Not all specifications are 100 percent tested.

Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions)

Sampling Frequency and playback Duration can vary as much as
±
2.25 percent over the commercial temperature range. For greater stability,
an external clock can be utilized (see Pin Descriptions)
[8]
Filter specification applies to the antialiasing filter and the smoothing filter. Therefore, from input to output, expect a 6 dB drop by nature of
passing through both filters.
