The ADI Chinese version datasheet is a translation of the English version datasheet, which introduces the ADuM120N/ADuM121N 3.0 kV rms dual channel digital isolator, including the functional diagram, product features, applications, etc.
The ADuM120N/ADuM121N are dual-channel digital isolators utilizing Analog Devices' iCoupler® technology. These devices integrate high-speed complementary metal-oxide semiconductor (CMOS) with single-chip air-core transformer technology to provide superior performance characteristics compared to optocouplers and other integrated couplers. They feature a maximum propagation delay of 13 ns at 5 V operation and pulse width distortion less than 3 ns.
These devices operate from 1.8 V to 5 V supply voltages, making them compatible with low-voltage systems while enabling level shifting across the isolation barrier. Unlike optocouplers, they ensure no DC offset during input logic transitions. The isolators offer two distinct fail-safe options and are available in an 8-lead SOIC package compliant with RoHS standards. This manual is written in Chinese.
| Data Rate | 150 Mbps (minimum) |
|---|---|
| Propagation Delay (Max, 5V) | 13 ns |
| Common-Mode Transient Immunity | 100 kV/µs (typical) |
| Operating Temperature | -40°C to +125°C |
| Supply Voltage Range | 1.8 V to 5 V |
The maximum propagation delay is 13 ns when operating at a 5 V supply voltage.
Yes, they are backward compatible; specifically, the ADuM120N0 is pin-compatible with the ADuM1285.
The datasheet lists UL certification (3000 V rms), CSA component acceptance notice, and CQC certification.
