Hi, I am new here with a power electronics background
I've been reading topics related to Isovu and other isolated probes and became quite curious as to why the isolation probes have taken a route for analog isolation.
Sounded like such optical isolation is not new, but calibration across temperature and offset is quite challenging.
What are the pros and cons of digital isolation? To clarify, I've added two block diagrams below.
Would bandwidth limitation be the main limiter for having an isolated amplifier + ADC + some form of fast communication back to FPGA?
