  • RE: ADS124S08: Accuracy

    Hi Sobin, Please check out the circuits in A Basic Guide to RTD Measurements as the circuits shown relate well to the ADS124S08. The accuracy will depend on how well you perform your system design, PCB layout and whether or not you do any calibration…

  • RE: ADS124S08: 3-Wire RTD

    Hi Bob, Thank you for your reply. I have question about ADC-RTD-CONFIG-CALC . R_PROTECT, R_MISC_H, and R_MISC_L are for protection in case of short circuit, etc, In an actual circuit, a 1k or several k resistor should be inserted. Is it correct…

  • RE: ADS1220EVM: RTD Pt100 3-wires test with ADS1220EVM configuration

    Resolved
    Hi, From the settings described above, IDAC is still turned off. The IDAC source needs to be turned on, otherwise there is no excitation source to bias the reference resistor and to generate a voltage across the RTD to be measured. We have some…

  • ADS131E08: Using ADS131E08 Dev Kit. ADC CONFIG Registers Read Back correctly. However, ADC RDATAC mode continuously returns same Incorrect Values

    Resolved
    Part Number: ADS131E08 Hi There, Long story short, I am able to write to the CONFIG registers and read them back. But when going into RDATAC mode, the ADC does not report correct data when sampling. Every channel gets stuck at one value and consistently…
