Raj,
I doubt that substitution of the IRF9520 for the IRF9513 is the problem. Many different P-channel MOSFETs could be successfully used.
A common mistake made with the XTR110 is to attempt its use in a two-wire transmitter application. Two-wire…

Hi Collin: My name is Ignacio Melchor, I'm from Mexico and currently I'm studying electronic engineering. When I knew the XTR111…
Hi Benjamin,
One possible issue, is that you are loading the "4wire_4p096_diode.txt" model file and attempting to change settings in 3-wire mode (PRG connected to VOUT). On my side, if I use the "4wire_4p096_diode.txt" model file, I leave JMP7 set to…
6675.Calibration = USB_DAQ + PGA309EVM.ppt Hello, Ian Williams.
I upload the 3-wire mode schematic for your review.
and i also upload .ppt file that including 4 wire mode calibration. it was downloaded from E2E community.
As you see, the 3-wire…
Hello,
Please refer to the attached PowerPoint slides for information on how to calibrate the PGA309 output voltage using the EVM software.
Best regards,

Hello Michael,
I apologize for the difficulty in configuring the PGA309EVM-USB and the lack of easily accessible documentation.
I believe that the problem you're having with the model file not "taking" is due to issues with User Account Control in…
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?
Other Parts Discussed in Thread: XTR116 , XTR115 I'd like to hear from anybody familiar with XTR115 or XTR116 on their recommendations how to convert 0-1000 Ohm linear resistance to 4-20mA...
Any circuit ideas or schematic examples other than going…
Other Parts Discussed in Thread: XTR116 The minimum output current of my 2-wire 4-20mA transmitter is greater than 4mA.
Why is that? How can I lower it?
Other Parts Discussed in Thread: ISO7340C , ISO7310C 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…
