Sign up using Email and Datwsheet. Post as a guest Name. 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?
Bridges, such as strain gauges, are one such sensor. AngeloQ 1, 1 5 Home Questions Tags Users Unanswered. Even an inexpensive TL will be okay at maximum conversion rate. I see no mention of internal reference in the Table of Contents. Some sensors are ratio-metric and thus tolerate variations in VREF. You can go dtasheet low as 1. There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign.

If you want tighter tolerance than the 0. Datashheet just survives with external ref. I went through another document which was 18MB and found no Vref. Spehro Pefhany k 4 The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion.
You could use the supply voltage however that is usually a pretty crude and noisy reference source.
78L03 – Three-Terminal Voltage Regulator
78l0 found the equations to calculate the result. You must provide the reference voltage, which will directly affect the accuracy of your ADC. Tie that to VDD.
