My understanding is that the digital versions have a fixed sensing distance - the object is either in-range or it isn't.Unless the platform is moving, and has an accurate position reference, this doesn't seem too useful for mapping purposes.
Only you can answer the question "which would be more suitable", based on the requirements you have, which you didn't share.
maybe digital is better as it can record the numbers, right?

Quotemaybe digital is better as it can record the numbers, right?Maybe it isn't better.Imagine being ordered to measure a room with a stick you have been told is 800mm long (though it may be as short as 700mm or as long as 900mm). You can only measure things as being "more than a stick" or "less-than-or-equal-to a stick".Do you think you'll be able to achieve that with your robot? (which you still haven't told us any more about)
I think you're in trouble. From what I can tell from the data sheet, that sensor is designed to tell when something comes within 800mm. It has a digital output, either one or zero depending on whether or not an object is within its detection range. From your previous comments I don't think that is what you want at all. I don't see any option but to order a different sensor.
