    Hello Juzer, If you do not want to create your own footprint using Altium's built-in footprint creation wizard inside of the PCB libraries, then you can try to find another device that shares the same "MSOP-10 + POWERPAD" (DGQ) footprint. Some other product offerings from the Precision...

    Hi Juzer, The XTR111 comes in two different packages to give customers a choice between a no-lead package (DRC) and a leaded package (DGQ). The DRC package is smaller (3mm x 3mm) due to the fact that it is a lead-less package and therefore will save some board space in the final application. The DGQ...

    Rob Mitrunen
    My customer asks: I plan on using 2 XTR111 and I would like to know if I can tie the 2 regulator out pins together so I can assure that I can supply enough current to the VDD2 side of my digital isolator. At worst case I would need 5.3mA and the XTR111 can supply up to 5mA so I know I wouldn’t...

    Hello, Unfortunately no TINA or SPICE model exists at this time for the XTR111. I apologize for the inconvenience. However, an EVM (evaluation module) is available for the XTR111 at this link which would allow you to evaluate the real-world behavior of the device. Best regards, Ian Williams...

    Hello Adnan, Thank you for your interesting in the XTR110/111 devices, and welcome to the TI E2E forums! Unfortunately, no TINA models exist for those devices. However, I would be happy to send you an XTR111 EVM (evaluation module) that you can use to get a feel for the real-world behavior of the...

  • Forum Post: Re: Generate 4-20mA signal without loop power with XTR115U

    Ian Williams
    Kenneth, Thank you for your interest in the XTR115, and welcome to the TI E2E forums. Because of the way the internals of the XTR115 operate, it is not possible for it to function without being loop powered. The operation you describe in your 3-wire mode requires a 3-wire transmitter such as the...

    Hello Michel, Thank you for your interest in the XTR110. However, based on your application I recommend a solution based on the XTR111 instead. While I believe that with properly-selected potentiometers, and time spent adjusting them, you would be able to achieve 4-20mA with 0-4.096Vin on the XTR110...

  • Forum Post: Re: XTR111 - Dynamic Performance question

    Ian Williams
    Hello Dave, Thanks for your question on the XTR111. The high-frequency noise is present at all times because of how the XTR111 uses multiple internal current sources to regulate the total output current . The 100nF capacitor placed at the output will greatly reduce the output noise. Measurements...

    Dear Dave, I am using XTR111 as output stage of my device, as a voltage to current converter as well as voltage to voltage converter. I am facing the problem of unexpected noise at output in current converter and in voltage to voltage converter, output has additional oscillations. Details are...

    Jayaraj A
    Dear Sir, Thanks for your reply. As per your suggestion, I connected a 100E resistance in series to the load of 100K (Potentiometer). My setup 2 diagram indicates the 100E put in series to the load. I didn’t find much improvement. As my resistance increases above 1K, my current regulation stops...

    Jayaraj A
    Dear Sir, Thanks for your reply. So I will conclude that XTR111 will be regulating its output current, only if it is within its compliance voltage. I will keep my output load, within that voltage range. Kindly have a view on my circuit and reply me if there is any bug. I will finalize with my set...

    Jayaraj A
    Dear Sir, I am using XTR 111 to convert my 0-3V (PWM based DAC) as 4-20mA. I am powering the XTR111 using a LM1117 ADJ @ 9V/ 1A (12V as I/P). Also I had retained the same circuit as mentioned in your reference design (evaluation board). The MOSFET which I am using is IRFL9014 ( Pchannel, -60V , 1...

    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...

  • Forum Post: XTR111, saturated output

    Stefano Infante
    Hello, I am using an XTR111 with the attached schematics; the IC is powered at 24 V, and the input is at 5 V (more precisely, it is 5.1 V). The problem is XTR111 output saturates at 19.4 mA, and I'm not able to understand why. I have four identical circuits, and all of them share the same problem...
