There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign. Post as a guest Name. Some sensors are ratio-metric and thus tolerate variations in VREF.

I see no mention of internal reference in the Table of Contents. Page 38 of datasheet shows a VREF pin. I went through another document which was 18MB and found no Vref. I will connect a voltage divider to the input of the ADC to measure the voltage.

You must provide the reference voltage, which will directly affect the accuracy of your ADC.

Tie that to VDD. Your reported voltage will only be as accurate as the VDD. The Varef pin has high impedance when the converter is not datahseet, however it draws 30pC typically per conversion.

Remember to filter and decouple dattasheet a RC circuit if you do not have a separate Vref regulator such as the 78L Sign up or log in Sign up using Google. Spehro Pefhany k 4 You can go as low as 1. A reasonable choice would be an external 2. 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? Email Required, but never shown. This is a link to the data sheet and a pic of the ADC operation conditions.

Bridges, such as strain gauges, are one such sensor.

I found the equations to calculate the result. AngeloQ 1, 1 5 ADC just survives with external ref. You could use the supply voltage however that is usually a pretty crude and noisy reference source.
