I would like to connect AD5254 and ADuM1250 side1.
When I check the logic level.
AD5254 input level threshold seems Vih>2.4V, Vil<0.8V.
ADuM1250 output level seems 600mV<Vol<900mV???
I couldn't understand ADuM1250 output logic level.
Can I connect AD5254 and ADuM1250 side1?
The ADuM1250 output level can be affected by the temperature which is the reason for the 600mV<Vol<900mV range. The communication between the ADuM1250 and the AD5254 might work at room temperature however it is hard to guarantee this over a wide temperature range.
Is there a reason you want to connect the AD5254 to side1 in particular?
Also if you wish to learn more about the operation of the ADuM1250 then please refer to the video belowHow I2C Isolators Work - YouTube
Please let me know if you have any further questions.
Thank you for the reply.
Need to connect side1...
Do you think we can use level snifter to clear the issue?
If yes, do you have recommend?
Great. I will look forward to hearing from you.
Currently I'm looking into an alternate solution and checking to see if the level shifter will cause any issues with the AD5254. I will get back to you sometime tomorrow.
At this point I would like to start an email conversation regarding this issue. It might be faster to resolve this issue that way.
