The ADuM2210 / ADuM22111 are 2-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 that are 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.Typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and 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 run atone-tenth to one-sixth the power of optocouplers at comparable signal data rates.The ADuM2210 / ADuM2211 isolators provide two independent isolation channels in a variety of channel configurations and data rates. They operate with the supply voltage of either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. The ADuM2210W and ADuM2211W are automotive grade versions.Similar to the ADuM3200 / ADuM3201 isolators, the ADuM2210 / ADuM2211 isolators contain various circuit and layout enhancements to provide increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge). The precise capability in these tests for either the ADuM3200 / ADuM3201 or ADuM2210 / ADuM2211 products is strongly determined by the design and layout of the user’s board or module.

The ADuM440x 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 ADuM440x 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 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The ADuM440x 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 ADuM440x provide low pulse width distortion (<2 ns for C grade). In addition, every model has an input glitch filter to protect against extraneous noise disturbances.The ADuM440x 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 ADuM440x are strongly determined by the design and layout of the user’s board or module.
