  • RE: ADS122U04EVM: Values of R77 and R79 for a PT1000 RTD

    Resolved
    The ADS122U04EVM was designed to be a generic solution to show many different sensor measurements. It may not be the best solution for you to use in your end system. The EVM implementation for 3-wire RTDs is showing a high-side reference that requires…

  • LAUNCHXL-CC26X2R1: Config the ADC sampling rate in sensor control

    Resolved
    Part Number: LAUNCHXL-CC26X2R1 Hi We would like to obtain the ADC value with a sampling rate of 256 Hz. Regarding the method #1 , we use the RTC tick interval to set the Sensor Control task tick interval. When Sensor Control collects the 256 ADC samples…

  • RE: Problem with IDAC compliance voltage

    Hi Ao, The ADS124S08 has two reference inputs. I would suggest using one reference for the ratiometric RTD and the other reference across the bridge sensor. Starting with the RTD first, the reference resistor circuit can be designed independently of the…

  • RE: ADS1120: It was supposed to receive the three data of 05, 42, 80, but received it was 0XFF high. What is the reason for this? Document: ads1120.txt

    Aiwen, In your design I do not see any obvious path for the IDAC current to flow into the RTD. Are you using one of the configurations shown in the data sheet for RTD measurement? If so, which one? I suggest you review https://www.ti.com/lit/an/sbaa275…

    Hi Paul, We resolve the problem by add a RC filter! Thank you for your help, if ADC designer has better solution please let us know( reply this mail). Best regards!

  • RE: ADS1248: Input section for 4xRTDs 4-wire measurement

    Hi Jendas, Jendas said: So it is posible making something like "reconnection" when there isn´t first RTD populated I'm not really sure what this question is asking, can you please clarify? Jendas said: And last, I am thinking about some additional…

  • RE: RTD 4-WIRE Signal Conditioner circuit solution

    Resolved
    Hello Ivan, As you have mentioned, at the input, the XTR105 is intended for a 2-wire RTD or 3-wire RTD probe/sensor. From the output perspective, the XTR105 is a two-wire current transmitter, producing a 4-20mA current output. Unfortunately, we do not…

  • RE: OPA2188:OPA2188: RTD linearizzation

    Resolved
    Hi Serhii, Can you please provide a full-schematic of the circuit above? How long are the connections between the amplifier and RTD probe? Is there an RC filter at the output of the amplifier between the ADC and op-amp circuit? Is the ADC the Atmega32A…
