iCoupler Digital Isolator Data Sheet ADuM1100 FEATURES GENERAL DESCRIPTION 1 High data rate: dc to 100 Mbps (NRZ) The ADuM1100 is a digital isolator based on Analog Devices Compatible with 3.3 V and 5.0 V operation/level translation Inc., iCoupler technology. Combining high speed CMOS and 125C maximum operating temperature monolithic air core transformer technology, this isolation Low power operation component provides outstanding performance characteristics 5 V operation superior to alternatives, such as optocoupler devices. 1.0 mA maximum 1 Mbps Configured as a pin-compatible replacement for existing high 4.5 mA maximum 25 Mbps speed optocouplers, the ADuM1100 supports data rates as high 16.8 mA maximum 100 Mbps as 25 Mbps and 100 Mbps. 3.3 V operation The ADuM1100 operates with a voltage supply ranging from 0.4 mA maximum 1 Mbps 3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge 3.5 mA maximum 25 Mbps asymmetry of <2 ns, and is compatible with temperatures up 7.1 mA maximum 50 Mbps to 125C. It operates at very low power, less than 0.9 mA of 8-lead SOIC N package (RoHS compliant version available) quiescent current (sum of both sides), and a dynamic current High common-mode transient immunity: >25 kV/s of less than 160 A per Mbps of data rate. Unlike other optocoupler Safety and regulatory approvals alternatives, the ADuM1100 provides dc correctness with a UL recognized patented refresh feature that continuously updates the output 2500 V rms for 1 minute per UL 1577 signal. CSA Component Acceptance Notice 5A VDE Certificate of Conformity The ADuM1100 is offered in three grades. The ADuM1100AR DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 and ADuM1100BR can operate up to a maximum temperature V = 560 V peak IORM of 105C and support data rates up to 25 Mbps and 100 Mbps, respectively. The ADuM1100UR can operate up to a maximum APPLICATIONS temperature of 125C and supports data rates up to 100 Mbps.
