Our customer needs reinforced insulation with ADuM6402.
They prefer to use Single Overlap Stitching Capacitor.
Is this OK for reinforced insulation?
Hello Thank you for your support always.
Our customer who is considering ADuM6402 has question about AN-0971.
There is a comment as below.
The rectifier circuit on the secondary side effectively doubles this frequency during the rectification process…
Thanks to your advice, the 360MHz EMI was improved 20dB.
But the result of 180MHz EMI was not good compared with the expectation.
They took a measure as below,
change from 2-layer to 4 layer
stitching capacitor: 30pF
Now April 2012
My problem is shown in http://ez.analog.com/thread/9318
But I can't understand the problem is gone in a new revision of chips.
My customer uses only 2 (1-1) ports though ADuM6402 has 2-2.
How to treat the pins which are not used.
Can they connect GND?
Our customer will use ADuM6402.
Could you give me your advice what do below difference of value of clearance and creepage mean ?
VDE document downloaded on your web site says below.
Clearance: Over 8.5mm
Creepage: Over 8.5mm
So he requests VDE document.
We check the document of VDE 0884 on your web site .
Its document P.1 says "valid until 2014 12 31"
(I reffer attachment).

Dont know? which will have the best results? I dont have a schematic or block yet.The layout is up to me. Its pretty straightforward though, I just need to withstand a 1500vDC working voltage continuously. The board will be FR-04. I would like an isolator…
