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

Evaluation Kits (1)
The EVAL-1CH2CHSOICEBZ supports single and dual channel standard data isolators in 8 lead SOIC packages. The evaluation board provides a JEDEC standard 8-lead SOIC_N and SOIC_W pad layout. This supports signal distribution, loopback, and loads referenced to VDDx or GNDx, as well as optimal bypass capacitance. Signal sources can conducted to the board through header pins or through edge-mounted SMA connectors (not supplied with board). Terminal blocks provide for power connections. The board includes 200 mil header positions for compatibility with Tektronix active probes (not supplied with board).
The board follows best printed circuit board (PCB) design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation design features are included on this board. In cases of very high speed operation or when ultralow emissions are required, refer to the AN-1109 application note for additional board layout techniques.
Features & Benefits
- Access to all 2 data channels
- Multiple connection options
- Support for Tektronix active probes
- Provision for cable terminations
- Support for PCB edge-mounted coaxial connectors
- Easy configuration
- Sample iCoupler digital isolator must be ordered separately:
