I will connect a voltage divider to the input of fatasheet ADC to measure the voltage. I see no mention of internal reference in the Table of Contents. Tie that to VDD. A reasonable choice would be an external 2.
I found the equations to calculate the result. There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign. Spehro Pefhany k 4 datashdet This is a link to the data sheet and a pic of the ADC operation conditions.
Your reported 7l803 will only be as accurate as the VDD. Some sensors are ratio-metric and thus tolerate variations in VREF. You could use the supply voltage however that is usually a pretty crude and noisy reference source. The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion. Have you examined the code-spread caused by external noise sources that datasheer into your sensor, or into your wiring between sensor and ADC, or into your ADC IC?
ADC just survives with external ref.
