ADUM1201WTRZ33-RL7

Overview

The ADUM1201WTRZ33-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7V to 5.5V and supports data rates up to 25Mb/s. The device features 2500Vrms isolation voltage and a minimum common-mode transient immunity of 25kV/µs. It is housed in an 8-SOIC package with a maximum propagation delay of 45ns. The component is AEC-Q100 qualified for automotive applications and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates two independent bidirectional channels using monolithic air-core transformer technology for galvanic isolation.
• Provides high-speed signal transmission with low propagation delay and minimal pulse distortion.
• Ensures robust noise immunity through high common-mode transient rejection capabilities.
• Supports flexible logic interface operation across varying supply voltage domains on both sides.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable signal isolation between microcontrollers and peripherals
• Medical equipment requiring safety-certified isolation barriers

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout or electrical variations. Confirm availability status as distribution listings may indicate limited stock. Ensure the 8-SOIC package matches PCB footprint requirements. Validate AEC-Q100 qualification if used in automotive contexts. Cross-reference datasheet revisions for any recent parameter updates.

Selection Notes

Select this component when bidirectional isolation is required for two separate signal paths. Compare data rate requirements against the 25Mb/s limit. Evaluate power consumption needs relative to the operating current specifications. Consider the SOIC-8 package constraints for board space. Verify compatibility with system voltage levels on both isolation boundaries.
