Forum Post: RE: ADS1248 SCHEMATIC FOR 2-WIRE PT1000 RTD

Hi Paolo,

This is close to what I think it should be, however I would move the common mode caps (the ones to ground on the analog inputs) to the other side of the input resistors so that there will be some filtering.

You may also want to add filtering to your reference inputs.  Even though the SBAA201 application note is based on 4-wire RTDs, the concept for matching for the ratiometric measurement is the same.

Best regards,

Bob B
