I have a question on how to use ADuM1250 with two isolated power supply.
My customer has the following wiring.
・SDA1 & SCL1 are connected to VDD1 (3.3V)through a 10k resistor.
・SDA2 & SCL2 are connected to VDD2(5V) through a 10k resistor.
・CLK is always input from the CPU, DATA is bidirectional.
・GND1 and GND2 are isolated.
In the above, is the circuit right?
It doesn't sound like there is anything wrong with what you have described. I'll just point out a few details of the ADuM1250...
