ADUM3211:  Dual-Channel Digital Isolator, Enhanced System-Level ESD Reliability

Информация о продукте

Статус продукта:Производство

The ADuM321x 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.

By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one- sixth the power of optocouplers at comparable signal data rates.

The two channels of the ADuM321x are independent isolation channels and are available in two channel configurations with two different data rates up to 10 Mbps (see the Ordering Guide). They operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. The ADuM321x isolators have a default output low characteristic in comparison to the ADuM3200/ ADuM3201 models that have a default output high characteristic. The ADuM321x are also available in 125°C temperature grade.

In comparison to the ADuM120x isolator, the ADuM321x 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 ADuM120x or ADuM321x 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.

Solving Isolation Challenges in Power Conversion Applications
This webcast will present solutions to isolation challenges in power conversion applications. Among the topics to be discussed are the limitations of traditional methods of isolation (such as utilization of optocouplers and pulse transformers) vs. more efficient and cost effective solutions that utilize digital isolators. If you are currently using optocouplers and pulse transformers, this is a webcast you should attend.
