ADUM5211ARSZ-RL7

Overview

The ADUM5211ARSZ-RL7 is a dual-channel digital isolator featuring an integrated isoPower isolated DC-to-DC converter. It provides signal isolation and power in a single package. The device supports data rates up to 100 Mbps with unidirectional channel polarity. It offers an insulation voltage of 2500 Vrms and a common-mode transient immunity of 25 kV/µs. The output of the internal converter is regulated between 3.15 V and 5.25 V, delivering up to 150 mW of output power. It operates within a supply voltage range of 2.7 V to 5.5 V for both sides and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates isoPower isolated DC-to-DC converter for simultaneous signal isolation and power delivery
• Provides dual-channel digital isolation with high common-mode transient immunity
• Supports data transmission rates up to 100 Mbps using NRZ signaling

Applications

• Industrial automation systems requiring galvanic isolation
