ADUM1200WTRZ35

Overview

The ADUM1200WTRZ35 is a discontinued digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features two unidirectional channels with a data rate of 25 Mbps and an isolation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7V to 5.5V and supports a wide operating temperature range from -40°C to +125°C. Packaged in an 8-SOIC surface-mount format, it offers a common-mode transient immunity of 25 kV/µs.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission across isolation barriers without requiring external transformers or optocouplers.

Applications

• Industrial process control systems
• Power management circuits
• Motor drive interfaces

Procurement Notes

This component has been officially declared obsolete by the manufacturer. Sourcing requires verification of stock availability through authorized distributors or surplus suppliers. Buyers must confirm that inventory represents genuine parts and check for potential counterfeit risks associated with end-of-life products.

Selection Notes

Designers should evaluate the ADUM1200WTRZ35 against current active alternatives due to its discontinuation status. Considerations include verifying pin compatibility and ensuring that replacement options meet the specific 25 Mbps data rate and 2500 Vrms isolation requirements of the original design.

Part Context

The ADUM1200WTRZ35 belongs to the ADUM1200 series of dual-channel digital isolators. This family leverages silicon dioxide (SiO2) insulation layers and micro-transformers to provide robust galvanic isolation for high-speed digital signals in electrically noisy environments.

Replacement Considerations

Public confirmed substitute part numbers: ADUM1200WTRZ, ADUM1200BRZ-RL7.
