ADUM3301CRWZ-RL

Overview

The ADUM3301CRWZ-RL is a triple-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 90 Mb/s. The device features bidirectional signal transmission with a typical propagation delay of 32 ns and rise/fall times of 3 ns. It provides reinforced insulation rated at 2500 Vrms and functions reliably across an industrial temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC-W, it draws approximately 108 mA of operating current.

Feature Summary

• Implements galvanic isolation via proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Supports bidirectional data flow across three independent channels simultaneously.
• Provides enhanced system-level ESD reliability compared to standard optical isolators.
• Operates on a single power supply rail ranging from 2.7 V to 5.5 V.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced electrical isolation for patient safety
• Communication infrastructure involving high-speed digital signal separation

Procurement Notes

Verify the specific suffix '-RL' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the component matches the 16-pin SOIC-W package dimensions for PCB layout compatibility. Cross-reference the part number against the latest Analog Devices lifecycle notices to confirm availability and obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when bidirectional isolation is required for three separate signal lines. Compare performance metrics such as propagation delay and common-mode transient immunity against unidirectional alternatives like the ADUM3300 series if directionality constraints exist. Evaluate power consumption requirements, noting the 108 mA typical current draw, against available supply rails. Ensure the 2500 Vrms insulation rating meets the specific safety standards mandated by the target application environment.

Part Context

This part belongs to the ADUM3300/ADUM3301 family of triple-channel digital isolators. It shares architectural similarities with the ADUM3300 series but differs in signal directionality capabilities. The family utilizes silicon dioxide-based micro-transformers to achieve isolation without the limitations of traditional optocouplers. This specific variant focuses on bidirectional applications within the broader interface IC category.

Replacement Considerations

The ADUM3300BRWZ-RL serves as a functional alternative but offers unidirectional isolation instead of bidirectional support. Verify channel count and data rate specifications remain compatible during substitution. Check if the replacement part maintains the same 16-pin SOIC-W footprint to ensure mechanical interchangeability without redesigning the host circuit board.
