Relative accuracy is the deviation of the analog value at any code from its theoretical value after the offset and gain errors
have been removed.
Offset nulled.

C. Determine absolute temperature by extrapolating from a calibrated value.
ADC performance is limited by the conversion noise floor, typically 300μV
P-P
. An external reference below 2.5V can
compromise the ADC performance.
Guaranteed from code 5 to 255.
