ADUM1300WTRWZ35-RL

Overview

The ADUM1300WTRWZ35-RL is a discontinued general-purpose digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features three independent channels with a data rate of 10Mbps and a propagation delay of 32ns maximum. The device provides 2500Vrms isolation voltage and 25kV/µs common-mode transient immunity. Operating on a single supply voltage between 2.7V and 5.5V, it is housed in a 16-SOIC package. This specific variant was designated for the automotive market but has been officially declared obsolete.

Feature Summary

• Utilizes iCoupler magnetic coupling technology to provide galvanic isolation without external magnetics
• Offers high common-mode transient immunity for reliable signal transmission in noisy environments
• Supports bidirectional data flow across three independent channels within a compact surface-mount package

Applications

• Automotive electronic systems requiring robust signal isolation
• Industrial communication interfaces such as RS-485 and CAN bus
• Motor control circuits needing isolated gate drive signals

Procurement Notes

This component is officially obsolete and no longer manufactured by Analog Devices Inc. Procurement should focus on verified parameter-equivalent substitutes like the ADUM1300WTRWZ. Buyers must confirm that replacement parts meet all original electrical specifications and package dimensions to ensure compatibility with existing designs.

Selection Notes

Designers should evaluate the ADUM1300WTRWZ as a direct functional replacement due to identical pinouts and electrical characteristics. Considerations include verifying the availability of the preferred packaging format and ensuring the substitute meets any specific automotive qualification requirements originally associated with the WZ35 suffix.

Part Context

The ADUM1300 series belongs to Analog Devices' iCoupler family of digital isolators. These devices integrate transformer-based isolation technology on-chip to replace traditional optocouplers. The ADUM1300 specifically targets applications requiring three-channel isolation with moderate data rates, offering a compact solution for system-level noise reduction.

Replacement Considerations

The ADUM1300WTRWZ is listed as a parameter-equivalent substitute. Verify that the standard tube or reel packaging of the replacement aligns with assembly requirements, as the original WZ35 suffix indicated specific automotive handling.
