The ADuM220N/ADuM221N/ADuM225N/ADuM226N1 are dual-channel digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion (PWD) of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.

The ADuM220N/ADuM221N/ADuM225N/ADuM226N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.0 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available, in which the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled. The ADuM220N0 is pin compatible with the ADuM2210 RW-16 package. The ADuM220N1 is pin compatible with the ADuM2200 RW-16 package. The ADuM221N0 is pin compatible with the ADuM2211 RW-16 package. The ADuM221N1 is pin compatible with the ADuM2201 RW-16 package.

Applications

  • General-purpose multichannel isolation
  • Industrial field bus isolation
  • Automotive systems
