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.

Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L Even an inexpensive TL will be okay at maximum conversion rate.

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.
