ADUM2286:  5 kV RMS Dual Channel Digital Isolators (Default Low, 1/1 Channel Directionality)

Product Details

Product Status:Recommended for New Designs

The ADuM2280/ADuM2281/ADuM2285/ADuM2286 (also referred to as ADuM228x in this data sheet) are 5 kV rms dual-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 superior to alternatives, such as optocoupler devices and other integrated couplers.

With propagation delay at 24 ns maximum, pulse width distortion is less than 2 ns for C grade. Channel-to-channel matching is tight at 5 ns for C grade. ADuM228x are available in two channel configurations with three different data rates up to 100 Mbps (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. Unlike other optocoupler altern-atives, the ADuM228x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions. When power is first applied or is not yet applied to the input side, the ADuM2280 and ADuM2281 have a default high output and the ADuM2285 and ADuM2286 have a default low output.
