5 kV RMS Dual Channel Digital Isolators Data Sheet ADuM2280/ADuM2281/ADuM2285/ADuM2286 FEATURES GENERAL DESCRIPTION 1 High isolation voltage: 5000 V rms The ADuM2280/ADuM2281/ADuM2285/ADuM2286 (also Up to 100 Mbps data rate referred to as ADuM228x in this data sheet) are 5 kV rms dual- Low propagation delay: 24 ns maximum channel digital isolators based on Analog Devices, Inc., iCoupler Low dynamic power consumption technology. Combining high speed CMOS and monolithic air Bidirectional communication core transformer technology, these isolation components 3 V to 5 V level translation provide outstanding performance characteristics superior to High temperature operation: 125C alternatives, such as optocoupler devices and other integrated High common-mode transient immunity: >25 kV/s couplers. Default high output: ADuM2280/ADuM2281 With propagation delay at 24 ns maximum, pulse width Default low output: ADuM2285/ADuM2286 distortion is less than 2 ns for C grade. Channel-to-channel 16-lead SOIC wide body enhanced creepage package matching is tight at 5 ns for C grade. The ADuM228x are Safety and regulatory approvals (pending) available in two channel configurations with three different UL recognition: 5000 V rms for 1 minute per UL 1577 data rates up to 100 Mbps (see the Ordering Guide). All models CSA Component Acceptance Notice 5A operate with the supply voltage on either side ranging from IEC 60601-1: 250 V rms (reinforced) 2.7 V to 5.5 V, providing compatibility with lower voltage IEC 60950-1: 400 V rms (reinforced) systems as well as enabling a voltage translation functionality VDE Certificate of Conformity across the isolation barrier. Unlike other optocoupler DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 alternatives, the ADuM228x isolators have a patented refresh V = 846 V peak IORM feature that ensures dc correctness in the absence of input logic Pin-compatible with ADuM220x and ADuM221x families transitions. When power is first applied or is not yet applied to APPLICATIONS the input side, the ADuM2280 and ADuM2281 have a default high output and the ADuM2285 and ADuM2286 have a default General-purpose, high voltage, multichannel isolation low output.
