ADUM1301WTRWZ35-RL

Overview

The ADUM1301WTRWZ35-RL is a general-purpose digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features three channels with a 2/1 input configuration in a 16-SOIC package. The device supports data rates up to 10Mbps and offers an isolation voltage of 2500Vrms. Key electrical parameters include a minimum common-mode transient immunity of 25kV/µs, maximum propagation delay of 32ns, and pulse width distortion of 3ns. It operates within a supply voltage range of 2.7V to 5.5V and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal transmission without optical components.
• Provides high common-mode transient immunity to ensure reliable operation in noisy environments.
• Features low propagation delay and minimal pulse width distortion for precise timing applications.

Applications

• Industrial automation systems requiring galvanic isolation
• Motor control circuits for feedback and gate drive signals
• Medical equipment needing safety-certified isolation barriers

Procurement Notes

Verify the specific suffix '35' against official manufacturer documentation to confirm if it denotes a specialized tape-and-reel variant or a discontinued status. Cross-reference the part number with current Analog Devices catalogs to ensure availability and check for any recent product change notices affecting this specific packaging or revision.

Selection Notes

Select this component when three isolated channels are required with high-speed performance up to 10Mbps. Ensure the application environment stays within the specified temperature range and that the 2500Vrms isolation rating meets the system's safety requirements. Compare against the standard WTRWZ version if reel packaging is not strictly necessary.

Part Context

This part belongs to the ADUM1301 series of digital isolators, designed for general-purpose isolation tasks. It is part of Analog Devices' portfolio of iCoupler products, which integrate transformer technology on-chip to provide compact, reliable isolation solutions compared to traditional optocouplers.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADUM1301WTRWZ and ADUM1301ARWZ-RL. Verify pinout compatibility and electrical specifications before substitution.
