    Ian Williams
    Hello Jimmy, Thank you for your interest in the XTR110. Currently, there are currently no models available for the device, but we could create a simple behavioral model for you. Would this be sufficient for your purposes? Best regards, Ian Williams

    Bruce Trump
    Chris, Answering your questions in your first post: A negative supply is required on the RCV420 to allow output voltage swing to 0V. Values of the trim components do not need to be changed when the input is configured for 0 to 5V input. A 30V rating on the output transistor should be adequate...

    James, You are correct - the internal structure of the XTR110 is shown on the first page of the data sheet so you could develop a simple model using an op-amp, transistor, and some resistors. However, the internal op-amp characteristics are not described in the data sheet, so picking a particular...

  • Forum Post: V to I Circuit with no common spans

    Marcos Carreras
    Hello everybody, I need to develop a V/I circuit. I think XTR110 is the best IC for this application, but need to know your thoughts about this: The current loop, need to drive 0-25mA output @ 0-10V input... Besides, need to implement another circuit to get 0-55mA @ 0-10V inputs for driving high impedance...

    Ian Williams
    Marcos, The XTR110 will work well for your application with non-standard spans. Simply make sure your external components meet the requirements of Equation 1 on p.6 of the data sheet, and pay close attention to the "Span Adjustment" and "Extended Span" sections. Best regards...

    mark etzler
    I have several XTR110 ICs on pc boards that will not put out 4mA when powered up. If I touch the Vref_sense pin (12), the output will start. I have resoldered all the pins and checked all the connections. The circuit is connected exactly like the circuit in Figure 1 of the data sheet, but with a 12...

    Mark, Thank you for the date code. The XTR110 devices you received are from a date range that is known to have start-up issues when the voltage reference is loaded. I have attached a copy of the letter we sent to customers when the issue was discovered and corrected in August of 2009. We apologize...

    I am making a 0-5V to 4-20 mA converter. I bought this IC and just for trial made the same circuit givein under Applications in the datasheet (0-10V to 4-20mA). However the circuit gives varying current for for varying Vcc but doesn't change with change in Vin as it should. I also tried...

    Hello Agraj, Thank you for your interest in the XTR110. I'm sorry to hear that you are seeing undesired behavior with the recommended circuit. Can you please let me know the markings on the device package? A photo of the package which clearly shows the markings would be best. Best regards...

    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...

    Ian Williams
    Hello Richard, The XTR110 is a 3-wire transmitter, so it must receive power from a dedicated supply pin instead of from a 4-20mA loop. This is optimal for the part's intended application, which is converting voltage input signals from a DAC or microcontroller into currents which control remotely...

    Ian Williams
    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...

    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

    Hi Collin, Thanks for fast reply and your kind advise. Yes, 100mA current is dangerous for human body. Thanks for your reminding, I will be careful. But 100mA just a maximum value of circuit, how much current output for, doctor must be according to the patient's feeling, increasing the current...

    Shrikant, Please check out the XTR110, XTR111 and XTR300. All of these devices are so-called "three-wire transmitters." They are intened for equipment with a power supply (your 24V) and "push" a current output signal to a distant load. It would required two ICs to handle to separate...

  • Forum Post: XTR110 span and zero adjust

    David Prince92104
    I am using two XTR110s in my product. The span adjust is barely large enough, and has a known interaction with the zero adjust. The zero adjust does not have enough range to make up for some voltage offsets that are created by the amplifers earlier in the circuit. I am using 100K ohm pot on the zero...

  • Forum Post: RE: XTR110 span and zero adjust

    David Prince92104
    Sorry about that. I have it set to the 0-5v input and 4-20mA output. R46 is a 10K ohm. The input, Pin 5, has a DC offset between 0.010 and 0.1 volts, this is making the zero adjust difficult. The highest voltage on pin 5 is about 4.7 volts, which is 19.6mA or so, that is fine. My PLC thinks 19.7mA...

    David Prince92104
    The data sheet does not specify a recommended value for the span and zero pots, it does use a 100K ohm pot in an example. I have been using 100K ohm pots in the production boards just fine. With a new revision I want to change the pots out for digital pots. So can I use a 25K or less preferable a 250K...

    My XTR110 is set up for 0-5vdc in and 4-20mA out, and powered by 24vdc. I have been using the IRF9510 Pmos, but noticed its VGS is to low. The temperature of the IRF9510 at 20mA was 109.5F. I then tired the FQP2P20 Pmos and at 20mA its max temperature was 111F. I also tried the FQP7P06, which had a max...
