ADuM3100 is a high-performance digital isolator with enhanced system-level ESD reliability. The device is packaged in an 8-lead SOIC and features low power consumption and high data rates, supporting 3.3 V and 5.0 V operation and level translation. It is suitable for applications such as digital fieldbus isolation, opto-isolator replacement, and computer peripherals.
The ADuM3100 is a digital isolator based on Analog Devices' iCoupler® technology, offering high‑speed CMOS performance with a voltage supply ranging from 3.0 V to 5.5 V, propagation delay under 18 ns, and operation up to 105 °C. It provides low‑power operation (less than 2 mA quiescent) and supports data rates up to 25 Mbps (AR grade) or 100 Mbps (BR grade), with enhanced system‑level ESD protection.
The datasheet includes detailed electrical specifications for 5 V, 3.3 V, and mixed‑voltage operation, package dimensions, pin configurations, safety and insulation ratings, recommended PCB layout, and ordering information. Regulatory approvals such as UL 1577 (2500 V rms) and VDE certifications are also listed.
