The ADuM1310/ADuM1311 is a triple-channel digital isolator that offers low power consumption, high temperature operation, high data rate, and high common mode transient immunity.
The ADuM1310/ADuM1311 are 3‑channel digital isolators based on Analog Devices' iCoupler® technology. They combine high‑speed CMOS with monolithic air‑core transformers to provide low‑power isolation, bidirectional communication, and level translation between 3 V and 5 V domains. Typical features include 0.38 mA per‑channel supply current, >25 kV/µs common‑mode transient immunity, and a 16‑lead SOIC package.
These devices are suited for general‑purpose multichannel isolation, SPI and data‑converter isolation, RS‑232/RS‑422/RS‑485 transceivers, and industrial field‑bus isolation. The datasheet lists UL 1577, CSA, VDE and DIN V VDE V 0884‑10 safety certifications and provides detailed electrical characteristics for 5 V, 3 V, and mixed‑voltage operation.
