ADUM5404CRWZ-RL

Digital Isolator 4CH 25Mbps 16Pin SOIC W T/R

Product Details

The ADuM5401/ADuM5402/ADuM5403/ADuM5404 devices are quad-channel digital isolators with _iso_Power®, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., _i_Coupler® technology, the dc-to-dc converter provides up to 500 mW of regulated, isolated power at either 5.0 V from a 5.0 V input supply or 3.3 V from a 3.3 V supply. This eliminates the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The _i_Coupler chip scale transformer technology is used to isolate both the logic signals and the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.

The ADuM5401/ADuM5402/ADuM5403/ADuM5404 isolators provide four independent isolation channels in a variety of channel configurations and data rates see the Ordering Guide for more information.

_iso_Power uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board PCB layout to meet emissions standards. Refer to Application Note AN-0971 for details on board layout considerations.
