Hi Neel Shah, I know that we have communicated on E2E in the past, but I don't recall seeing the schematic or layout. Passing the IEC tests can be a challenge. Resolving this could require schematic or PCB layout changes. One of my colleagues has designed boards specific to thermocouple and RTD inputs and testing the boards through a variety of the IEC tests using the ADS124S08. We had hoped to post those findings earlier this year but due to shifting priorities this has been delayed. Earlier my colleague posted this application note that may be helpful. Many of the same concepts would apply to pass the IEC tests. To be of further help I would need to see the schematics and board layout. Best regards, Bob B
