    Ian Williams
    Hello Dennis, Thank you for your interest in the XTR105, and welcome to the TI E2E forums! Firstly, I calculated slightly different resistor values for your input range of 0-90C. I have attached my calculations page in MathCAD to this post. My values are as follows: Rz = 100 Rg = 70.346...

    Neil Albaugh
    Matias; I suspect that you are violating the XTR112 common mode voltage range-- check the data sheet specifications and circuit diagrams. I do not see Rcm in your circuit diagram.

    Martin Kriz
    Hello I have a problem with linearity chip XTR116 , my circuit is connected according to FIGURE 1. Nonlinearity chip is 0.003%, potentiometer have nonlinearity under 0.1%. I need all nonlinearity under 0.1%, but when I measure this circuit, nonlinearity is bethween 0.3 to 0.4%. Y ou know, what could...

  • Forum Post: XTR115 beter temperature stable

    Marien Vermeulen
    Hi, I think I can use teh XTR115, it seems one of the best transmitters. But I need to improve the temperature stability; drift. As far I have calculated the device is for a 100 degrees temperature drift typical 0.0475% and maximal 0.275%. The datasheets give no curves about the offset and gain...

    Hi Collin I hope you are very well... With your help, I built a PCB with the XTR111 , based on the following diagram: I used the MMBT2907 pnp transistor and the mosfet IRFR9014, I checked all the conections very good, but the problem is when I supply the voltage of input fron 0 to 5 volts, the...

    Cawen Gu
    Dear Sir: We use XTR115 in our product,VCC supply MCU(MSP430F4270),MCU output DACout voltage to drive XTR115 which can output 4~20mA.MCU current is 1.8mA. But we find that XTR115 output current is not stable(4mA-->6.16mA),and No periodic.We test XTR115 output Vreg and VCC Volatge,Their volatge...

    Matt Graham1
    I could not find an appropriate Spice/component model for the XTR106 4-20mA current transmitter IC. Has anyone created a Spice/component model, or know of a similar chip (TI or otherwise) that can be used for modeling? Thanks, -Matt

    Paul Schmidt
    I have an XTR105 application that I have been making on and off for many years. It involves monitoring a potentiometer and reporting the pot position via 4-20mA. Basically, I would just place the pot element in between one of the constant current outputs and the RC network that returns current to I-ret...
