Email Required, but never shown. The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion. I will connect a voltage divider to the input of the ADC to measure the voltage. Page 38 of datasheet shows a VREF pin.
Bridges, such as strain gauges, are one such sensor. Spehro Pefhany k 4 AngeloQ 1, 1 dqtasheet There is a paper 7803 this, for a thermistor of Kohm; check on robustcircuitdesign. Some sensors are ratio-metric and thus tolerate variations in VREF. Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L You could use the supply voltage however that is usually a pretty crude and noisy reference source.
Your reported voltage will only be as accurate as the VDD. Sign up using Facebook.
I see no mention of internal reference in the Table of Contents. ADC just survives with external ref. Even an inexpensive TL will be okay at maximum conversion rate. Sign up datassheet Email and Password.

This is a link to the data sheet and a pic of the ADC operation conditions. I found the equations to calculate the result. Sign up or log in Sign up using Google.
Tie that to VDD. I went through another document which was 18MB and found no Vref. You can go as low as 1. 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?
