Hi Shrikant,
1. Please attach a schematic.
2. The error in output current could be because of the ohmic tolerence of the resistor in series with pin 2 (Iin) of the XTR116.
3. Using two diodes in series might not be a good idea to drop voltage from 5V…
Hello User,
We'll need to read through the PIC datasheet to understand if it will properly interact with the XTR116.
While we're reviewing the MCU, please provide a more complete schematic of the PIC that shows how you intend to power the VCC/GND…
Dear Collin,
Thanks for the quick and valuable reply.
I will go through these datasheets and try to build a schematic which will satisfy my requirements. I will get back to you with upadate on this.
Also I forgot to update you on our last discussion regarding…
Hi Collin,
Thank u so much for answer.
1) I feed system from a single source (Vloop). I did circuit isolation. But I'm using the ground of Vloop sources. So I'm using as of the system GND. Does theproblem ? Or how I'm gonna use ?
2) What is…
Hello Magne,
Please take a look at one of our "CerTIfied" precision reference design, TIPD126, that provides radiated immunity testing data using the XTR117 current loop transmitter. The XTR117 is very similar to the XTR116 but without the internal…
Hello Alan,
Thank you for your question, and welcome to the TI E2E forums!
The simplest way to achieve 4-20mA out with a resistance pot at the input would be by using the XTR115 or XTR116, since both parts have an internal voltage reference that could be…
Hello Kris,
This is an interesting application, could you provide some information about what type of sensor it interacts with as well as what type of control equipment the 250uA - 450uA output is connected to? We can start a private conversation if you…
Hello,
We reviewed the product datasheet and agree that there doesn't appear to be any limiting factors for operating the device in this limited low output current range. However, to be sure we setup the circuit in the lab and configured it for a…
The ESD ratings of the XTR116 are:
Human Body Model: 2000V
Machine Model: 300V.
I'm looking to implement a low-power 2-wire current loop where my signal current will range about 250uA to 450uA (not 4-20mA) using the XTR116.
The data sheet seems to say the xtr116 can do this under these conditions…
Hello Kris,
Yes, the blue trace uses the transistor internal to the XTR116.
Perhaps the discrepancy with/without the transistor is simply due to the polarity of the bias currents and/or offset voltage in the circuit and depending on the device one may…
Hi,
What is the ESD rating of the XTR116 current loop transmitter?
Thanks!
