Part Number: ADS1261-Q1

Hello,

I am looking for 3 wire and 4 wire RTD design using ADS1261-Q1. The datasheet provides only information on 3 wire circuit. Kindly guide us for 4 wire RTD design.

Hi Vidya Patil,

Yes this is certainly possible. Please refer to our RTD design guide for more information:https://www.ti.com/lit/an/sbaa275a/sbaa275a.pdf?ts=1700077324364&ref_url=https%253A%252F%252Fwww.google.com%252F

You can adapt the 3-wire and 4-wire circuits described in that app note for your purposes.
