Part Number: XTR117
Good morning,
We are designing a new product using the XTR117 IC.
Everything works as intended but I recently read this line from "Application Report SBOA107B Using the XTR115 with the PGA309 to Generate 4mA to 20mA Output" : a minimum value of R2 = 10kΩ should be used to insure the XTR115 stability.
Here is the related schematic :
I do not see any mention of minimum value for this resistor in the XTR datasheet and since we are using a similar schematic I wonder if this information applies to the XTR117 and is up to date?
Our prototype design is using a 1k resistor and we do not have any stability issue at the moment but should we consider redesigning that part for higher resistor value ? Is there a true risk by using 1k input resistor value that could leads to instability in some boards (I know that this change seems trivial but it will imply modification of our PCB and then internal cost/delay before production)?
Best regards.
