Hot-selling and scarce ADUM3210TRZ Dual-Channel Digital Isolators SOP8 spot stock

Product Descriptions

The ADuM321x1 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 onesixth 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.
