ADUM3401TRWZ-EP

Overview

The ADUM3401TRWZ-EP is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mbps. The device provides 2500 Vrms isolation voltage and exhibits a common-mode transient immunity (CMTI) of 25 kV/µs. Key electrical parameters include a maximum propagation delay of 100 ns and typical rise/fall times of 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Quad-channel architecture with bidirectional signal transmission capability
• Integrated magnetic coupling for galvanic isolation without external transformers
• Enhanced system-level ESD reliability for robust industrial operation

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering interface circuits

Procurement Notes

Verify the specific suffix 'EP' indicates enhanced product specifications or qualification status distinct from standard commercial variants. Confirm RoHS compliance and lead time requirements directly with authorized distributors, as availability may be restricted. Ensure the 16-SOIC package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when high channel density and moderate speed are required in a compact surface-mount package. Compare against the ADUM3401CRWZ if higher data rates near 90 Mbps are necessary, noting the trade-off in power consumption. Verify that the 2500 Vrms isolation rating meets the safety standards of your specific application environment.

Part Context

This part belongs to the ADUM3401 series of quad-channel digital isolators. It shares the same functional block diagram and pinout configuration as other variants in the family, such as the ARWZ and CRWZ versions. The primary distinctions lie in performance grades, temperature ranges, and specific manufacturing qualifications associated with the EP designation.

Replacement Considerations

Direct substitutes include ADUM3401ARWZ and ADUM3401CRWZ. Verify that the replacement variant meets the required data rate and isolation voltage specifications for your circuit design.
