Hi,
I want to use ADuM4160 for my FTDI isolation. I designed a circuit, but I'm not sure if it's completely correct. I'd like someone to verify it for me.
I want to know, is my current connection in low speed or high speed mode? This is a design I referenced from an ADI forum, which claims that it is high speed. But in the data sheet, it says "Selects full speed slew rate, timing, and logic conventions when SPU is high". But my connection does not connect the SPU pin to GND to make it low speed?
Another question, I use a DC-DC isolation module (R05P05S_X2_R8) to power the right side of the ADuM4160, is this feasible? The left end of my DC-DC isolation module is GND_RAW and Vusb_RAW, and the left end of the ADuM4160 is GND_RAW1 and Vusb_RAW1. Can this connection make the ADuM4160 work properly?
Best,
Junzhe
