♠ Dual-Channel Digital Isolators, Enhanced System-Level ESD Reliability
The ADuM3210-EP/ADuM3211-EP1 are dual-channel digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives such as optocoupler devices.
The ADuM3210-EP/ADuM3211-EP isolators provide two independent isolation channels in two channel configurations with data rates up to 25 Mbps (see the Ordering Guide). They operate with 3.3 V or 5 V supply voltages on either side, providing compatibility with lower voltage systems, as well as enabling voltage translation functionality across the isolation barrier. The ADuM3210-EP/ADuM3211-EP isolators have a default output low characteristic in comparison to the ADuM3200/ADuM3201 models, which have a default output high characteristic.
In comparison to the ADuM1200-EP isolator, the ADuM3210-EP/ADuM3211-EP isolators contain various circuit and layout changes providing increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge). The precise capability in these tests for either the ADuM1200-EP or ADuM3210-EP/ADuM3211-EP products is strongly determined by the design and layout of the user’s board or module. For more information, see the AN-793 Application Note, ESD/Latch-Up Considerations with iCoupler Isolation Products.
Refer to the ADuM3210/ADuM3211 data sheet for additional application and technical information.
