  • [FAQ] Does TI have integrated 4-20mA transmitters for inputs from RTDs?

    • Resolved
    Does TI have integrated 4-20mA transmitters for inputs from RTDs (resistive temperature detectors)?

  • [FAQ] Why does my 2-wire 4-20mA transmitter output not reach the full 20mA?

    • Resolved
    Why does my 2-wire 4-20mA transmitter output not reach the full 20mA? When I change the load resistance or decrease the supply, the output changes. What can I do to fix this?

  • RE: AMC1311-Q1: AMC1311

    Hi Sunil, I was hoping to get more time with this but, one thought I had would be to try and use something like an XTR112 or XTR114 to try and realize what it is that you want to do here. My thinking was that you could use the differential output of...

  • XTR112: The output current of the circuit can not keep constant with different RL

    TI Thinks Resolved
    Part Number: XTR112 Hello I have a problem with XTR112 , my circuit is according to datasheet XTR112 / FIGURE 1. RTD(PT1000) Input, Current Excitation,input resistant is adjusted in range 700Ω - 1200Ω. When the input resistant is constant...

  • RE: [FAQ] What is a 2-wire 4-20mA current transmitter?

    2-wire transmitters are loop powered devices most commonly used to monitor a remote process with no access to a local supply. Two analog signal wires carry both the analog output signal, and power for the sensor/monitoring circuitry and transmitter. The...

  • [FAQ] Are there reference designs that can help me build a 4-20mA transmitter?

    • Resolved
    Are there reference designs that can help me build a 4-20mA transmitter? Where can I find them? How do I incorporate IEC protection into my design?

  • [FAQ] Can I use multiple XTR devices if I have multiple DAC outputs or multiple sensors that share a supply and ground?

    • Resolved
    I have multiple sensors going into a DAC with multiple output channels. Can I use multiple XTR devices to transmit the 4-20mA current signals for each sensor?

  • [FAQ] The minimum output current of my 2-wire 4-20mA transmitter is greater than 4mA.

    • Resolved
    The minimum output current of my 2-wire 4-20mA transmitter is greater than 4mA. Why is that? How can I lower it?

  • [FAQ] Can I use a 2-wire 4-20mA transmitter with a sensor or microcontroller that uses its own supply?

    • Resolved
    2-wire 4-20mA transmitters are loop powered, and the sensor and its associated circuitry are supplied by the transmitter. Is it possible to use a sensor or microcontroller that uses a separate supply as the input to my 2-wire transmitter?

  • [FAQ] What types of applications or end equipment are 4-20mA transmitters used in?

    • Resolved
    In what applications are 4-20mA transmitters used? What types of end equipment are 4-20mA transmitters a part of?
