Hello everyone, I'm using an ADUM4160 for isolating an ECG device for my university project, the fact is that I'm designing a ECG system portable and I want to supply my device through the USB port, I have a 3.3v micro controller so I'm using a 3.3v regulator but I've only seen examples of how to connect the ADUM4160 using and external source for supplying the regulator but I don't want that, I want to use the USB port for supplying all the device.
In my design I have something like this:
Is this a wrong design?, what do you recommend?
I'm a little bit confused with this device, These are my first steps with USB communication so I've been struggling a little bit. I hope someone can help me. Thanks.
bye the way, What is the difference between VDDx and VBUSx?
