ADUM3201CRZ-RL7

Overview

The ADUM3201CRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and provides an isolation voltage of 2500 Vrms. The device supports data rates up to 25 Mb/s with a typical propagation delay of 45 ns. It features a common-mode transient immunity of 25 kV/µs and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, it offers enhanced system-level ESD performance.

Feature Summary

• Dual-channel architecture for independent signal isolation
• Magnetic coupling technology for galvanic isolation
• Enhanced system-level ESD reliability
• High common-mode transient immunity

Applications

• Industrial process control systems
• Medical equipment signal isolation
• Power metering applications
• Inverters and motor drives

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the CRZ designation corresponds to the commercial temperature grade (-40°C to +85°C) and RoHS compliance status required for your assembly. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability, as availability may vary by region.

Selection Notes

Select this component when bidirectional communication is not required, as it is unidirectional. Compare against the ADUM3201W series if automotive qualification (AEC-Q100) or extended temperature ranges are necessary. Ensure the 2500 Vrms isolation rating meets the safety standards of the target application. Verify that the 25 Mb/s data rate suffices for the specific bus speed requirements.

Part Context

This part belongs to the ADUM3201 family of iCoupler digital isolators. These devices integrate high-speed digital isolation on a single CMOS chip, replacing traditional optocouplers and transformers. The family includes variants with different temperature grades and channel configurations, offering a compact solution for noise reduction and ground loop elimination in mixed-signal environments.

Replacement Considerations

The ADUM3201ARZ-RL7 serves as a verified alternative within the same family, offering similar functionality but potentially differing in temperature rating or specific electrical characteristics. Verify pin compatibility and isolation ratings before substitution.
