I see no mention of internal reference in the Table of Contents.
Spehro Pefhany k 4 You can go as low as 1. Bridges, such as strain gauges, are one such sensor.

Some sensors are ratio-metric and thus tolerate variations in VREF. Email Required, but never shown.
I found the equations to calculate the result. Sign up or log in Sign up using Google. Page 38 of datadheet shows a VREF pin. You must provide the reference voltage, which will directly affect the accuracy of your ADC. Your reported voltage will only be as accurate as the VDD.

A reasonable choice would be an external 2. Have you examined the code-spread caused by external noise sources that couple into your sensor, or into your wiring between sensor and ADC, or into your ADC IC? You could use the supply voltage however that is usually a pretty crude and noisy reference source. Sign up using Facebook.
If you want tighter tolerance than the 0. This is a link to the data sheet and a pic of the ADC operation conditions. There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign. The Varef pin has high impedance when the converter is not operating, however it datasheeg 30pC typically per conversion. ADC just survives datasheef external ref. Even an inexpensive TL will be okay at maximum conversion rate.
