Other Parts Discussed in Thread: DAC8750, XTR111
Tool/software:
I am looking to use (presumably multiple) TPS2661X for protection on a 3-wire transmitter. Figure 9-14 of the datasheet is for a 3-wire transmitter but only shows protection for the analog output. What is the correct usage to fully protect the transmitter on all lines, especially from all combinations of potential mis-wiring.
I am assuming something akin to figure 9-11 with a TPS26612 on both the analog out and on the 24V supply. Each line using a TVS to ground. Would 24V supply also run through a single diode and then feeding both Vs+ pins?
I am currently looking to use a DAC8750 for the current loop. Is it correct that this IC does not have a sense input to implement the feedback compensation indicated in Figure 9-14?
