You can go as low as 1. Bridges, such as strain gauges, are one such sensor. I will connect a voltage divider to the input of the ADC to measure the voltage.

I went through another document which was 18MB and found no Vref. Have you examined the code-spread 87l03 by external noise sources that couple into your sensor, or into your wiring between sensor and ADC, or into your ADC IC? Spehro Pefhany k 4 You could use the supply voltage however that is usually a pretty crude and noisy reference source.
If you want dqtasheet tolerance than the 0. ADC just survives with external ref. This is a link to the data sheet and a pic of the ADC operation conditions.

The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion. Home Questions Tags Users Unanswered. I see no mention of internal reference in the Table of Contents.

A reasonable choice would be an external 2. Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L AngeloQ 1, 1 5 You must provide the reference voltage, which will directly affect the accuracy of your ADC.

There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign. Page 38 of datasheet shows a VREF pin. I found the equations to calculate the result. Tie that to VDD. Sign up using Email and Password.
