The ADuM5400 is a quad-channel digital isolator with integrated DC-DC converter, regulated 5 V output and 500 mW output power.
The ADuM5400 quad‑channel digital isolator integrates an isoPower® isolated DC‑DC converter, providing a regulated 5 V output and up to 500 mW of isolated power. Based on iCoupler® technology, it offers four independent isolation channels with data rates up to 25 Mbps and high common‑mode transient immunity.
The datasheet includes detailed specifications, pin configurations, typical performance curves, power consumption analysis, and safety and regulatory information such as UL 1577 isolation rating and IEC 60747‑5‑2 compliance.
| Regulated Output Voltage | 5 V |
|---|---|
| Maximum Output Power | 500 mW |
| Supply Voltage Range (VDD1) | 4.5 V – 5.5 V |
| Output Rise/Fall Time | 2.5 ns (10 %‑90 %) |
