The ADuM250N/ADuM251N/ADuM252N are 5-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 of less than 4.5 ns at 5 V operation. Channel to channel matching of propagation delay is tight at 4.0 ns maximum.
The ADuM250N/ADuM251N/ADuM252N 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 1.7 V to 5.5 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 by which the outputs transition to a predetermined state when the input power supply is not applied.
- General-purpose multichannel isolation
- Serial peripheral interface (SPI)/data converter isolation
- Industrial field bus isolation

Evaluation Kits (1)
The EVAL-5CH6CHSOICEBZ supports 5-channel and 6-channel iCoupler® standard data isolators in a 16-lead SOIC package. The evaluation board provides a JEDEC standard, 16-lead SOIC_N and SOIC_W pad layout. This layout supports signal distribution, loopback, and loads referenced to the VDDx or GNDx planes, as well as optimal bypass capacitance. Signal sources can be conducted to the evaluation board through header pins or through edge mounted SMA connectors (SMA connectors must be ordered separately). Screw terminal blocks on the evaluation board provide power connections.
The evaluation board includes 0.2 inch header positions for compatibility with active probes (probe header pins must be ordered separately).
The evaluation board follows best PCB design practices for 4-layer boards, including a full power plane and ground plane on each side of the isolation barrier. No other electromagnetic interference (EMI) or noise mitigation design features are included on the evaluation board. In cases of high speed operation, or when ultralow emissions are required, refer to the AN-1109 Application Note for additional evaluation board layout techniques.
