ADUM1200WSRZ33

Overview

The ADUM1200WSRZ33 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 25 Mb/s. The device features unidirectional signal transmission with a 2/0 channel configuration in an 8-SOIC package. Key electrical specifications include a maximum propagation delay of 150 ns, a typical power consumption of 4.3 mA per channel, and an isolation voltage rating of 2500 Vrms. It maintains a common-mode transient immunity of 25 kV/µs and functions across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Implements iCoupler magnetic coupling technology for high-speed digital isolation without external magnetics.
• Provides bidirectional capability through specific pin configurations despite the 2/0 directional designation.
• Ensures robust signal integrity with high common-mode transient immunity ratings.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment interfaces needing certified isolation barriers.
• Automotive electronics adhering to AEC-Q100 qualification standards.

Procurement Notes

Verify the suffix '33' against official Analog Devices documentation to confirm it denotes a specific tape-and-reel packaging variant or regional distribution code rather than a functional deviation. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the source provides valid traceability documents for automotive-grade components.

Selection Notes

Select this component when a dual-channel, unidirectional isolator with low power consumption is required. Compare against the ADUM1201 if bidirectional communication on both channels is necessary. Consider the SOIC-8 footprint constraints and verify that the 2500 Vrms isolation barrier meets the specific safety requirements of the target application environment.

Part Context

This part belongs to the ADuM120x family of dual-channel digital isolators. It shares the core iCoupler architecture with variants like the ADUM1200WSRZ and ADUM1200WURZ. The primary distinction lies in the packaging format and specific ordering suffixes defined by Analog Devices for different manufacturing sites or reel types.

Replacement Considerations

The ADUM1200WURZ serves as a parameter-equivalent alternative offering similar electrical characteristics in a tube package. For bidirectional applications, the ADUM1201 series is the direct functional counterpart within the same family.
