Product Number: ADum347x
Hello,
I would like use ADuM3472 as an digital isolator for serial communication in railway application. I would like to ask if it is possible to use different voltage 5V on middle of transformer and VDDA supplied by 3.3V. From my point of view it shouldn't be a problem because internal switches are designed to withstand 5V. I need to Do that solution due to 3.3V communication on primary side and available transformers on market/on stock.
Thank you very much for answer
