Part Number: ISO224
This might be a silly question, but is there any problem that might arise when tying the negative output of ISO224 to the low-side ground, GND2? My original plan was to do this because the microcontroller that I'm using will be referenced to the same low-side ground (MSP432P401R launchpad), so the output is essentially "single-ended," if you will.
However, this is not the route that the datasheet specifies (or the EVM for that matter). It seems that the output is used differentially in these applications.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Tom Hendrick:
Thanks, that's really helpful. My issue's almost resolved, but which output buffer is preferable from the EVM? OPA277 or TLV6001?
Since my launchpad is powered by a 5 V source with its own ground that all inputs need to be referenced to, would I need to use TLV6001 since it can be operated with a single-ended supply (as in the EVM), or can OPA277 also be operated using a single-ended 5 V supply?
