This document describes the features and characteristics of the iCoupler Digital Isolator ADuM1100, including high data rate, compatibility with 3.3V and 5.0V operation/level translation, low power operation, high common-mode transient immunity, etc.
The ADuM1100 is a high‑speed digital isolator based on Analog Devices' iCoupler technology. It supports 3.0 V‑5.5 V supply voltages, provides propagation delays under 18 ns, and operates from –40 °C to +125 °C (depending on grade). The device is offered in an 8‑lead SOIC_N package and meets UL, CSA, VDE and DIN safety approvals.
Typical applications include digital field‑bus isolation, opto‑isolator replacement, computer peripheral interfaces, microprocessor system interfaces, and general instrumentation and data‑acquisition systems. The datasheet includes electrical specifications for 5 V, 3.3 V, and mixed‑voltage operation, package dimensions, pin descriptions, and ordering information.
