ADUM1400CRW-RL

Overview

The ADUM1400CRW-RL is a quad-channel digital isolator manufactured by Analog Devices Inc., housed in a 16-SOIC package. It provides four unidirectional channels with magnetic coupling technology, supporting data rates up to 90 Mb/s and offering an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing typical power supply currents of 18 mA on the driver side and 70 mA on the receiver side. It features a propagation delay of 100 ns and maintains high common-mode transient immunity at 25 kV/µs. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent unidirectional signal paths for robust channel isolation
• Utilizes silicon dioxide and coil-based magnetic coupling for reliable signal transmission
• Ensures high common-mode transient immunity to prevent noise-induced errors
• Supports wide operating voltage ranges compatible with various logic families

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing galvanic isolation for sensor data
• Power electronics monitoring circuits demanding high-voltage separation
• Medical equipment requiring strict electrical safety isolation standards

Procurement Notes

Verify that the specific suffix 'CRWZ-RL' matches the required tape-and-reel packaging configuration for automated assembly processes. Confirm that the AEC-Q100 qualification status aligns with your automotive or industrial reliability requirements. Ensure the SOIC-16 footprint dimensions are compatible with your PCB layout constraints. Check for any recent product change notices regarding manufacturing site transitions or material composition updates.

Selection Notes

Select this component when unidirectional signal flow is sufficient for the application architecture. Consider the 90 Mb/s data rate limit against your system's bandwidth requirements. Evaluate the 2500 Vrms isolation barrier strength against your circuit's voltage stress levels. Compare the power consumption characteristics against other isolator technologies if thermal management is a critical design constraint.
