ADS124S08EVM: Difference between EVM and datasheet for 3-wire RTD

Part Number: ADS124S08EVM
Other Parts Discussed in Thread: ADS124S08

Dear Technical Support Team,

I'd like to configure 3-wire RTD with ADS124S08.

Comparing 5.1.1.1 RTD Configurations and 7.3 Schematic evaluation board circuit, the component connections circled in red are different.
Which is correct?

5.1.1.1 RTD Configurations

 

7.3 Schematic

Best Regards,

ttd

    Hi ttd,

    I don't see a meaningful difference between the connections in the datasheet versus the EVM.

    The only difference that I see is that Figure 14 is setup to show only a 3-wire RTD connection, while section 7.3 in the EVM shows connections for 2-, 3-, and 4-wire RTDs. This is why there are additional components in section 7.3 e.g. C70
