GENERAL DESCRIPTION

The ADuM6400/ADuM6401/ADuM6402/ADuM6403/

ADuM64041 are quad-channel digital isolators with isoPower?,

an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler? technology, the dc-to-dc converter provides

up to 400 mW of regulated, isolated power at either 5.0 V or

3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply

at the power levels shown in Table 1. These devices eliminate

the need for a separate, isolated dc-to-dc converter in low

power, isolated designs. The ADuM6400/ADuM6401/ADuM6402/ADuM6403/

ADuM6404 isolators provide four independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide for more information).

isoPower 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. See the

AN-0971 Application Note for board layout recommendations.
