Combining high speed feature that continuously updates the output signal. CMOS and monolithic transformer technology, this isolation The ADuM3100 is offered in two grades. The ADuM3100AR component provides outstanding performance characteristics and ADuM3100BR can operate up to a maximum temperature superior to alternatives, such as optocoupler devices. of 105C and support data rates up to 25 Mbps and 100 Mbps, Configured as a pin-compatible replacement for existing high respectively. speed optocouplers, the ADuM3100 supports data rates as high In comparison to the ADuM1100 digital isolator, the ADuM3100 as 25 Mbps and 100 Mbps. contains various circuit and layout changes to provide increased The ADuM3100 operates with a voltage supply ranging from 3.0 V capability relative to system-level IEC 61000-4-x testing (ESD/ to 5.5 V, boasts a propagation delay of <18 ns and an edge asym- burst/surge). The precise capability in these tests for either the metry of <2 ns, and is compatible with temperatures up to 105C. It ADuM1100 or ADuM3100 is strongly determined by the design operates at very low power, less than 2.0 mA of quiescent current and layout of the users board or module.
