  • Forum Post: XTR110 not working properly

    raj balraj
    i designed a circuit which converts 8 bit digital data to 4 to 20mA transmitter. In the datasheet it is mentioned that we need to use the mosfet IRF9513.I did not had the IC in indian market. so i used an alternate ic IRF9520 in which the current raring is greater than the previous mentioned one.As a...

    Juliana Campos Silva
    Hello, My name is Juliana and I'm working with a XTR108 but, unfortunately I'm having problems with this circuit. When I test it, the output through the Rload is always the same. We I change the temperature on the PT100, this voltage has to vary at the same proportion, but it's is not...

    Myles Bohon
    I'm trying to set up an XTR110 op amp to convert a 0-10V to 4-20mA signal for a electronic pressure regulator. I've wired the circuit as shown in Fig. 1 of the white pages, with the substitution of two PNP transistors in place of the p-channel MOSFET transistor (as shown in Fig. 5 of the white...

    Hi Collin, Thanks for your response. You are absolutely right, I meant Fig. 2. I am using a 0.047uF capacitor. The above diagram shows the circuit I have built. I apologize if its difficult to read, I do not have a background in electrical engineering. Thanks for your help, Myles

    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...

    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

  • Forum Post: XTR105 negative V-in

    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...
