Product Details

The ADuM4400W/ADuM4401W/ADuM4402W are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics that are superior to the alternatives, such as optocoupler devices and other integrated couplers.

The ADuM4400W/ADuM4401W/ADuM4402W isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 3.135 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The ADuM4400W/ADuM4401W/ADuM4402W isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.

This family of isolators, like many Analog Devices isolators, offers very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at comparable data rates up to 10 Mbps. All models of the ADuM4400W/ADuM4401W/ADuM4402W provide low pulse width distortion (<3.5 ns for WB grade). In addition, every model has an input glitch filter to protect against extraneous noise disturbances.

The ADuM4400W/ADuM4401W/ADuM4402W contain circuit and layout enhancements to help achieve system-level IEC 61000-4-x compliance (ESD/burst/surge). The precise capability in these tests for the ADuM4400W/ADuM4401W/ADuM4402W are 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.
