GENERAL DESCRIPTION
Figure 3. ADuM6201 The ADuM6200/ADuM6201/ADuM62021 are dual-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc

is a small form factor, total isolation solution. 5.0 5.0 400 The ADuM6200/ADuM6201/ADuM6202 isolators provide two 5.0 3.3 330 independent isolation channels in a variety of channel configura- 3.3 3.3 132 tions 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. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329; other patents are pending.
