Hi,
I don't have any specific examples of how the DAC161P997 can be used to build a four-wire transmitter. However, I can point you to some blog posts on how a four-wire transmitter design is put together. These blog posts are on the Precision Hub and are broken up by how the output and power are isolated in in the transmitter design.
Most of the designs I've see for the DAC161P997 are for applications where there is some loop power, and the DAC is supplied from a subregulated voltage from the loop power. Are you looking at the DAC161P997 specifically, or are you looking for a four-wire transmitter design?

Hi,
I think that the blogs are a good start to designing a 4-wire system. I don't know of any specific reference designs for a 4-wire transmitter. However, the circuits shown in the blog are rather complete.
I'll close this thread for now, but if you have other questions, feel free to post back.
