Email Required, but never shown. Tie that to VDD.
There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign. Post as a guest Name. A reasonable choice would be an external 2. The Varef datawheet has high impedance when the converter is not operating, however it draws 30pC typically per conversion. If you want tighter tolerance than the 0. You could use the supply voltage however that is usually a pretty crude and noisy reference source.

You can go as low as 1. Sign up using 78ll03. Some sensors are ratio-metric and thus tolerate variations in VREF. Bridges, such as strain gauges, are one such sensor. Home Questions Tags Users Unanswered.
Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L This is a link to the data sheet and a pic of the ADC operation conditions.
You must provide the reference voltage, which will directly affect the accuracy of your ADC. 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? Even an inexpensive TL will be okay at maximum conversion rate.

AngeloQ 1, 1 5 Page 38 of datasheet shows a VREF pin. I went through another document which was 18MB and found no Vref.
