ADuM144x Family intrinsic Safety Certification

Hi,

I will have a check whether we have the plan to get the certifications, and for your second question you will find the answer in Table 21 below.

ADuM1440/ADuM1441/ADuM1442 have the default high output state if input is unpowered and ADuM1445/ADuM1446/ADuM1447 have the default low output state.

Neil

Is there an update on the ATEX, UL or CSA certs for the ADuM144x product line?

Hello J Merrill

We are currently not getting additional US versions of the ATEX and IECEX certifications.  However, we can provide the test report from CSA/SIRA under NDA which contains the internal construction detail that will let you use the existing certifications in the US.

I will contact you directly to discuss this further.

As far as the pin descriptions, these assumed that the part was powered and functional.  So there is no difference when the part is in operation.

The exception to this is when the enables do not match across the part, and the device goes into its default state when powered.  The default value comes into play when the refresh is turned off on the transmit side, bit it is expecting refresh on the receive side.  The part thinks the transmit side is off, and goes into default.  This is forbidden in the table, so the states do not reflect it.  It will not damage the chip to operate like this, it just give unpredictable results.

Best Regard,

Hello,

We are interested in the ATEX/IECEX certification of ADuM144x for a new product.

Is it possible to get the test report from CSA/SIRA with the internal construction detail? We could sign an NDA.

Hi,

We've already got an NDA signed with Analog Devices. Is it possible to get the information? We've asked for it through your spain distributor (Arrow), and we didn't managed to get it. It seems that lately is very difficult to get any support from Analog Devices.

Hi Miguel,

The IECEx Certificates of Conformity are available at www.iecex.com when you click "Online Certificates" and then search for the "ADuM144x".   

All available certificates are posted on the Safety and Regulatory Compliance page.

Hi,

What I need is what was offered to jmerrill in the previous answer:

"we can provide the test report from CSA/SIRA under NDA which contains the internal construction detail that will let you use the existing certifications in the US."

We need the test report not the certificate.

Best regards and thanks for your kind attention,

Miguel Lopez
