ADUM1400CRWZ-RL

Overview

The ADUM1400CRWZ-RL is a quad-channel digital isolator utilizing iCoupler technology. It provides four independent channels with unidirectional signal transmission. The device operates on a single power supply ranging from 2.7 V to 5.5 V. Key electrical parameters include a data rate of 90 Mbps, isolation voltage of 2500 Vrms, and common-mode transient immunity of 25 kV/µs. Propagation delay is typically 27 ns per channel. The component is housed in a 16-pin SOIC_W package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates four isolated digital channels within a single compact package
• Utilizes iCoupler magnetic coupling technology for galvanic isolation
• Provides high common-mode transient immunity for noisy environments
• Supports wide operating temperature ranges for industrial applications

Applications

• Industrial process control systems requiring isolated communication
• Medical equipment needing patient isolation barriers
• Power metering and energy monitoring interfaces
• Automotive sensor interface circuits

Procurement Notes

Verify the specific suffix 'CRWZ-RL' to confirm the reel packaging and commercial grade temperature rating. Ensure compatibility with the target PCB footprint for the 16-SOIC_W package. Confirm that the required data rate and isolation voltage meet system specifications before ordering.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are needed in a small form factor. Compare against ADUM1401 if higher data rates are required. Consider the 2500 Vrms isolation rating for safety compliance. Verify power consumption requirements as the device draws current proportional to data rate.

Part Context

This part belongs to the Analog Devices ADuM1400 series of quad-channel digital isolators. It is designed to replace bulky optocouplers in space-constrained designs. The series offers improved performance in terms of speed, power consumption, and reliability compared to traditional optical isolation technologies.

Replacement Considerations

Direct pin-compatible replacements may include other variants within the ADuM1400 family, such as ADUM1400ARWZ-RL for extended temperature ranges. Verify datasheet specifications for any functional differences between revisions.
