ADUM1200WTRZ35-RL7

Overview

The ADUM1200WTRZ35-RL7 is a discontinued digital isolator from Analog Devices Inc. utilizing iCoupler magnetic coupling technology. It features two unidirectional channels with a data rate of 1 Mbps and an isolation voltage of 2500 Vrms. The device operates on a supply voltage of 2.7V to 5.5V, housed in an 8-SOIC package. Key electrical parameters include a maximum propagation delay of 150 ns, typical rise/fall times of 10 ns, and a minimum common-mode transient immunity of 25 kV/µs. It supports an operating temperature range of -40°C to 125°C.

Feature Summary

• Employs iCoupler magnetic coupling technology for signal transmission without optical components.
• Provides robust galvanic isolation with high common-mode transient immunity.
• Supports bidirectional logic isolation within a compact surface-mount package.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Automotive electronics demanding high reliability and wide temperature operation

Procurement Notes

This component has been officially declared obsolete by the manufacturer. Verification of end-of-life status is required before integration into new designs. Sourcing should focus on authorized distributors for surplus stock or qualified replacement parts that maintain pin compatibility and electrical specifications.

Selection Notes

Designers should evaluate alternative active components from the same family, such as the ADUM1200WTRZ series, which offer identical functional characteristics. Selection criteria must prioritize channel count, isolation voltage ratings, and data speed requirements to ensure seamless transition without redesigning the isolation barrier.

Part Context

Part of the ADUM1200 series, this device represents Analog Devices' iCoupler technology line. It serves as a general-purpose digital isolator designed to replace traditional optocouplers in applications where size, power consumption, and reliability are critical factors for system performance.

Replacement Considerations

The ADUM1200WTRZ is listed as a parameter-equivalent substitute. Verify package dimensions and electrical tolerances against the original specification sheet to ensure mechanical and functional compatibility in existing layouts.
