You could use the supply voltage however that is usually a pretty crude and noisy reference source.

Even an inexpensive TL will be okay at maximum conversion rate. 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? I see no mention of internal reference in the Table of Contents.

Your reported voltage will only be as accurate as the VDD. Sign up using Facebook. Home Questions Tags Users Unanswered. You must provide the reference voltage, which will directly affect the accuracy of your ADC. Sign up using Email and Password. I went through another document which was 18MB and found no Vref. There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign.
AngeloQ 1, 1 5 If you want tighter tolerance than the 0. You can go as low as 1.
Email Required, but never shown. Bridges, such as strain gauges, are one such sensor. Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L Post as a guest Name.
ADC just survives with external ref. The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion. Spehro Pefhany k 4 Tie that to VDD.
