INTRINSIC SAFETY
The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 support intrinsic safety for IS to IS applications under
IEC 60079-11, and carry ATEX and IECEx certifications. These devices do not currently support IS to non IS galvanic isolation
applications due to the minimum insulation requirements of IEC60079-11.
Product Conformity Certificate
Sira 16ATEX2265U and IECEx SIR 16.0091U
Special Conditions for Safe Use
These components are certified to comply with IEC 60079-11:2011. When one of these components is used in equipment, the component
is to be fitted on a PCB inside a suitable enclosure and recertified as equipment. The creepage and clearance distances across the isolating
component have been evaluated, but the distances to other circuitry remain the responsibility of the user of the certified equipment.
This assembly is an isolating component between separate intrinsically safe circuits. It is recommended that the assembly be connected to
suitably certified intrinsically safe circuits considering the entity parameters in Table 16.
