Hi Sir:

 

We use ADuM1250 on our project, and the signal chain as below.

if follow above signal chain, we can not get any ADC's data through I2C Bus. (no ACK, please see below figure)

But if we bypass any one of ADuM1250 (ADC side), then the I2C work normally.

(Cut 5V, and provide 3.3V to ADC,  please see below figure)
