ADUM1401WTRWZ33-RL

Overview

The ADUM1401WTRWZ33-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for galvanic isolation. It features a 2500 Vrms insulation voltage and supports data rates up to 90 Mb/s with a propagation delay of 34 ns. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing typical currents of 31 mA and 57 mA per side. It is housed in a 16-SOIC package, rated for operation between -40°C and +125°C, and holds AEC-Q100 automotive qualification.

Feature Summary

• Provides galvanic isolation via magnetic coupling technology
• Supports high-speed data transmission up to 90 Mb/s
• Features unidirectional channel configuration
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive electronic control units requiring isolated communication
• Industrial systems needing high common-mode transient immunity
• Power monitoring circuits with isolated signal paths

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout or voltage level compatibility, as suffixes often denote specific packaging or electrical variations. Confirm current availability status through authorized distributors, as lifecycle changes may affect procurement options. Ensure the component meets RoHS compliance requirements for your region.

Selection Notes

Select this component when unidirectional isolation is required for four independent channels. It is suitable for designs demanding high speed (90 Mb/s) and robust isolation (2500 Vrms). Consider the 16-SOIC package constraints and the specified operating temperature range. Verify that the power consumption profiles align with system thermal budgets.

Part Context

This part belongs to the ADUM1401 series of general-purpose digital isolators. It shares the core magnetic coupling architecture with other variants in the family but differs in channel directionality, data rate, and packaging format. The series is designed to replace bulky optocouplers in modern interface applications.
