It does not say that because the whole idea of converting ADC result to voltage is silly
This is how I see this - may be we will get everyone to agree
I reckon we had got there in Reply #75 and my summary in Reply #79.Here's to the next 30 replies ...R
2. dividing by 1023 statistically minimizes the maximum absolute error and thus it's fair then to assume that you get statistically a better approximation of your true original input value V if you use 1023
The "statistical minimum" is obtained when the value is assumed to be in the middle of the bucket: VEST = (x + 0.5) * VREF / 1024
I agree with that, and we established that way back when.And, assuming that is also your view I don't understand the purpose of your Reply #102...R
THIS IS WHY I THINK 1023 IS BETTER THAN 1024 (and you get a nice 5V for 1023)
The figure is wrong because the datasheet says that 1023 is obtained for a value that is not Vref (Vcc in your figure) but Vref-Vref/1024, so the last segment, the one that has Vcc as upper limit, doesn't exist.
