Hello,
In the datasheet, Cvcc is recommended (One place says "should", another says "must"??) to be no smaller than 680nF. I have a nitpick clarification question so as to avoid potentially overdoing that capacitor. Is this datasheet stating that the selected value should be at least 680nF (and a good quality ceramic), or that the actual capacitance value itself (after tolerance, temperature, applied voltage, etc.) needs to always stay above 680nF?
Thanks.
