Other Parts Discussed in Thread: XTR108
Hello,
I would like to know what is the maximum value for the R_LOAD connected to the current loop of XTR108. I didn't find any mention of it in the datasheet.
Thanks in advance.

Hello,
I'm still working in a project that uses the XTR108 as a temperature transmitter. We design the circuit to work with it, but isn't work. When I turn on the voltage source, there are no voltage signal through…

Hi Rizwan,
We offer the XTR108 as a two-wire transmitter/conditioner specifically designed for RTD applications. It does signal conditioning and linearization in the desired range.
Please take a look at the data sheet, and let me know if you have any further…
Part Number: XTR111 Other Parts Discussed in Thread: XTR117 , XTR116 , XTR115 , XTR108 Hi Team,
Customer would like to know:
TR115 supports HART signal. However, the high power consumption of the customer's project makes the two-wire system unsatisfactory…
Part Number: PGA309 Other Parts Discussed in Thread: XTR108 Hello,
i will reopen the topic to check if any documentation has been released for RTD usage.
I would like to use PGA309 as RTD 4-wire excitation and signal conditioner.
Would it be possible…
Hi Saeed,
There are many options to design the thermistor circuit, and convert the voltage to 4-20mA current loop. I need to have clear direction how you want to proceed.
Your thermistor application is operating such a wide temperature range from ~700kΩ…
Rupesh,
The XTR108 is a very different device than the XTR105. Do you need the the flexibility offered by the digital circuitry of the XTR108? Without knowing anything about your application I can't comment on whether you'd benefit from using the XTR108…
Hi Steve,
You are correct that the XTR108's PGA has a minimum gain of 6.25. In order to interface an external 0.5-4.5V source to the XTR108 you would need an attenuator on the input. If input loading is an issue for your application, you may…
