ADUM1401WSRWZ33-RL

Overview

The ADUM1401WSRWZ33-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates on a 2.7V to 5.5V supply and provides 2500Vrms isolation voltage. The device features a data rate of 1Mbps, with a maximum propagation delay of 100ns and typical rise/fall times of 2.5ns. It offers a minimum common-mode transient immunity of 25kV/µs and supports a pulse width distortion of up to 40ns. Designed for surface mount installation in a 16-SOIC package, it functions within a temperature range of -40°C to 105°C.

Feature Summary

• Integrates four independent unidirectional channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides robust noise immunity with a minimum common-mode transient immunity rating of 25kV/µs to withstand high dv/dt environments.
• Supports flexible power supply configurations with dual-side operation ranging from 2.7V to 5.5V without requiring isolated auxiliary supplies.

Applications

• 16-bit fully isolated output modules
• Isolated voltage output modules
• Isolated 4 mA to 20 mA current loop transmitters

Procurement Notes

Verify the specific suffix '33' against the official Analog Devices datasheet to confirm pinout or electrical parameter variations compared to standard variants. Confirm availability status as distribution listings may indicate limited stock or restricted supply conditions. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring four isolated digital channels with moderate speed requirements around 1Mbps. It is suitable for applications needing high common-mode transient immunity and bidirectional logic compatibility within a single 16-pin package. Consider the thermal performance and operating temperature range relative to the intended industrial or automotive environment constraints.

Part Context

This part belongs to the ADUM1401 series of quad-channel digital isolators manufactured by Analog Devices. It shares architectural similarities with the ADUM1400 and ADUM1402 but differs in channel directionality and configuration options. The series leverages silicon dioxide insulation layers to achieve high-voltage isolation without the bulk of traditional optocouplers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-references through official manufacturer substitution guides rather than generic distributor lists to ensure functional equivalence.
