To get best accuracy of the ADC you need to level shift the signal from 2.72 - 4.52 to become 0 - 1.8 v.
put the vref of the ADC = 1.8 v , this way you get better accuracy. 1.8/256 increments. Since your reading is linear you can do some maths to scale it to whatever you want displayed as some of the guys stated above. Regards Mahmood |
