This document describes the features and characteristics of Quad-Channel Digital Isolators ADuM1400/ADuM1401/ADuM1402, including low power operation, 5V and 3V operation, bidirectional communication, high temperature operation, high data rate, precise timing characteristics, etc.
The ADuM140x series are four-channel digital isolators based on Analog Devices' iCoupler® technology. These components combine high-speed CMOS and monolithic air core transformer technology to provide superior performance compared to traditional optocouplers, eliminating issues like uncertain current transfer ratios and temperature effects.
Available in three models (ADuM1400, ADuM1401, ADuM1402), these devices support data rates up to 90 Mbps with precise timing characteristics. They operate on supply voltages ranging from 2.7 V to 5.5 V and include features such as bidirectional communication, level translation, and a patented refresh feature for DC correctness.
| Maximum Data Rate (CRW Grade) | 90 Mbps |
|---|---|
| Common-Mode Transient Immunity | >25 kV/μs |
| Pulse-Width Distortion (CRW Grade) | < 2 ns |
| Supply Voltage Range | 2.7 V to 5.5 V |
| Package Type | 16-lead SOIC |
They are based on Analog Devices' iCoupler® technology, combining high-speed CMOS and monolithic air core transformer technology.
Yes, the document lists bidirectional communication as one of the key features.
