Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi Electronx,
I believe the designer of the XTR111-2EVM included the 1kΩ resistor so that the input will be weakly pulled to ground in the case that Vreg is disconnected (J3 open) and there is no input connected at the Vin terminal. This ensures that…
Part Number: XTR111-2EVM Other Parts Discussed in Thread: XTR111 , I am building a V to I converter using XTR111 and need to look at the GERBER files for the XTR111 EVM board to match exactly the traces
I would use just a part of the board where the XTR111…
Part Number: XTR111 Other Parts Discussed in Thread: XTR117 Hi Dear,
As shown in the figure, is suitable for use with three wire sensors. Is it possible to use it as a two wire sensor? How to connect the circuit? Is there any reference material for 4…
Part Number: XTR111
Hello Team, This thread is a continuation of my previous post Link . We are using XTR111 in one of our projects. Attached is the schematic for the same.
We need both analog voltage (0 to 10V) and analog current ( 4 to 20mA ) outputs. So we…
Part Number: XTR111 Other Parts Discussed in Thread: OPA189 , TINA-TI , OPA828 , OPA328 , OPA827 , OPA140 , OPA3S328 , OPA320 Hello,
as you can see in the picture below in the datasheet of the XTR111 it says that the minimum current output of the integrated…
Hi Nikhil,
Nikhil F said: In shared document https://www.ti.com/lit/pdf/tidub12 , in equation-6 considered ITUE_ XTR = 0.036% where as per equation-4 it is 0.034%. Does it Typo mistake or it is addition of equation-4 and equation-5 values?
The total uncalibrated…
Part Number: XTR111
I am working based on this reference design of xtr111. Here I was going to take the P channel Mosfet and pnp transistor from the proposed bill of materials list, but the materials mentioned in digikey are out of stock. Can you recommend…
Part Number: XTR111 Hi Experts,
May I ask if the set-pin connect with a resistor to adjust the current? From the datasheet, I＝Vin/R×10, if Vin=3.3V, and we connect a 6.5kohm resistor, we could get the 20mA current?

Part Number: XTR111 Hi,
I've done a design with XTR111 and i've seen it needs a mosfet(BSP170P L6327) that is recommended for it, but i can't use it because i haven´t got space to put it. could you advice me one smaller?
Thanks for all…
Hello Luis, Thank you for your reply. The user guide of the XTR111 recommends using a bipolar TVS diode (MPN - SMAJ40CA ). The same output terminal act as the analog voltage/analog current output. So for 4-20mA output, the voltage can be more than 10V but…
