I am trying to generate a digitized sine signal by feeding sine pattern to the 10 bit DAC.

I need you help to suggest me the suitable number of samples, it is definitely the more samples taken beyond the Nyquist condition the more it approach the ideal shape, I believe the number of samples is the same quantity that we describe the oversampling ration from it. However, more samples means more memory and also it will affect the speed of operation since we need to push these sample digits to the DAC one by one

In the other hand the wave shape is also constrained to the DAC resoution, so I am thinking that might be even big number of samples will become a waste.

How can I know the best number of samples (or the oversampling ratio) that suits my 10 bit DAC resoution?

Note: For simplicity I am using the online sine lookup table generator below:
