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? Your reported voltage will only be as accurate datashret the VDD. Tie that to VDD. Bridges, such as strain gauges, are one such sensor.

The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion.

I will connect a dqtasheet divider to the input of the ADC to measure the voltage. Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L Sign up using Email and Password.

You could use the supply voltage however that is usually a pretty crude and noisy reference source. Email Required, but never shown.

If you want tighter tolerance than the 0. ADC just survives with external ref. Some sensors are ratio-metric and thus tolerate variations in VREF. A reasonable choice catasheet be an external 2.

I found the equations to calculate the result. AngeloQ 1, 1 5 There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign.
