The ADuM131x are 3-channel digital isolators based on Analog Devices, Inc. iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide 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, maximum operating 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 iCoupler also offers higher channel densities and more options for channel directionality.

The ADuM131x isolators provide three independent isolation channels in a variety of channel configurations and data rates up to 10 Mbps (see the Ordering Guide). All models 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. All products allow the user to predetermine the default output state in the absence of input VDD1 power with a simple control pin. Unlike other optocoupler alternatives, the ADuM131x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.

APPLICATIONS

  • General-purpose multichannel isolation
  • SPI interface/data converter isolation
  • RS-232/RS-422/RS-485 transceiver
  • Industrial field bus isolation
