ADUM3400TRWZ-EP-RL

Overview

The ADUM3400TRWZ-EP-RL is a quad-channel digital isolator utilizing iCoupler technology, featuring monolithic air core transformers and high-speed CMOS. It provides 2500Vrms isolation with a data rate up to 90Mbps and common-mode transient immunity of 25kV/µs. The device operates on a 3V to 5.5V supply, supports bidirectional communication, and includes an output enable function. It is housed in a 16-lead SOIC package and rated for operation from -40°C to 105°C.

Feature Summary

• Enhanced system-level ESD reliability per IEC 61000-4-x standards
• Bidirectional communication with 3.3 V/5 V level translation capability
• Precise timing characteristics including low pulse width distortion
• High common-mode transient immunity for noisy environments

Applications

• General-purpose multichannel isolation
• SPI and data converter isolation
• RS-232, RS-422, and RS-485 transceiver isolation
• Industrial field bus isolation

Procurement Notes

Verify the specific suffix 'EP' indicates enhanced product specifications or military-grade screening as defined by Analog Devices. Confirm the '-RL' suffix denotes reel packaging configuration. Ensure the component matches the required isolation voltage and data rate specifications for the target application before procurement.

Selection Notes

Select this component when high channel density and precise timing are required. It is suitable for applications needing robust ESD protection and bidirectional data transfer. Consider the power consumption at the target data rate and verify that the 16-SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the ADuM3400 series of quad-channel digital isolators. It leverages iCoupler technology to replace traditional optocouplers, offering superior performance in speed, size, and power efficiency. The EP variant typically signifies enhanced reliability or specific qualification standards within the Analog Devices portfolio.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM340x family. Verify if standard commercial versions meet the specific environmental or reliability requirements implied by the EP designation. Ensure substitute parts support the same 90Mbps data rate and isolation voltage ratings.
