ADUM1201WTRZ35

Overview

The ADUM1201WTRZ35 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation voltage with a data rate of 1Mbps and a common-mode transient immunity of 25kV/µs. The device operates on a 2.7V to 5.5V supply, features unidirectional channels in an 8-SOIC package, and supports temperatures from -40°C to 125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission without external magnetics
• Provides robust galvanic isolation with high common-mode transient immunity
• Supports wide operating temperature range suitable for industrial environments

Applications

• Industrial process control systems requiring isolated communication
• Medical equipment needing reliable patient isolation barriers
• Power metering applications with high-voltage separation needs

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm replacement part numbers such as ADUM121N1WBRZ match required specifications. Check datasheet revisions for any parameter updates before finalizing procurement decisions.

Selection Notes

Select this component when low-speed isolation is sufficient. Consider the ADUM1201WTRZ variant if higher data rates are needed. Ensure the 8-SOIC package fits the design constraints. Verify thermal management requirements for the specified operating temperature range.

Part Context

This part belongs to the Analog Devices iCoupler family, offering chip-scale isolation. It replaces older discrete isolation solutions by integrating transformers on silicon. The W suffix indicates a specific tape and reel packaging configuration distinct from standard tube packaging.

Replacement Considerations

The ADUM121N1WBRZ is listed as a similar substitute. Verify pin compatibility and electrical parameters against the original datasheet before implementation.
