Part Number: ISO3082
Hello, dear hotline.
My customer' s looking for a replacement part for isolated RS485 - ADM2483. He looks at ISO3082 but there're some doubts.
Their design is half-duplex, 3.3V on one side and 5V on the other side (485 line).
Does smb have maybe fighting guide comparison between ISO3082 and ADM2483 power consumption.
It's important to know what is current consumption on VCC1 (and also the consumption on all inputs from VCC1 side), when VCC2 is fully turned off (=0) & DE RE are also turned off
In other words customer wants the minimal current consumption on VCC1 in device standby mode (in turned off condition). He can't see this parameter in ADM2483 datasheet.
It will be great if you could provide such comparison between ISO and ADM.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Dan Kisling:
The ISO3082's power consumption performance is not quite as good as ADI's. However it does have better ESD and CMTI performance.
If you are open to a more discrete option (isolator + RS485 transciever) I can recommend a lower power option than the ISO3082.
Let me know if I've answered all of your questions.
Thank's for your fast reply. I'll keep in mind your suggestion about a discrete solution and forward it to customer.
Best regards, Anastasia
