Other Parts Discussed in Thread: XTR111,
I have a query regarding Hart communication. Can we interface XTR111 4-20mA output current IC with Dac8740H for Hart communication ?

XTR devices can interface with a DAC that has a typical voltage output. The DAC8740H has a HART output, so it is not able to be used with the XTR by itself.
One solution is to add a DAC that has a typical output and connect that to the XTR, where the DAC8740H can be included as well, similar to this reference design.
Let me know if there are any other questions,
