GENERAL DESCRIPTION ADM2582EBRWZ

The ADM2582E/ADM2587E are fully integrated signal and

power isolated data transceivers with ±15 kV ESD protection

and are suitable for high speed communication on multipoint

transmission lines. The ADM2582E/ADM2587E include an

integrated isolated dc-to-dc power supply, which eliminates the

need for an external dc-to-dc isolation block.
