ADUM3200TRZ-EP-RL7

Overview

The ADUM3200TRZ-EP-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mbps. The device features a propagation delay of 45 ns maximum and offers a common-mode transient immunity (CMTI) of 25 kV/µs. It provides 2500 Vrms isolation voltage and functions reliably across an operating temperature range of -40°C to +105°C. Packaged in an 8-SOIC format, this component is designed for robust signal transmission in electrically noisy environments.

Feature Summary

• Employs iCoupler magnetic coupling technology for high-speed digital isolation without external magnetics
• Provides enhanced system-level ESD reliability and high common-mode transient immunity
• Supports bidirectional data transmission with low propagation delay characteristics

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment interfaces demanding high safety isolation standards
• Power electronics monitoring circuits in harsh electrical environments

Procurement Notes

Verify the specific suffix 'EP' indicates engineering production or enhanced performance variants compared to standard commercial grades. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed data rates up to 25 Mbps are required alongside robust isolation capabilities. Consider the 25 kV/µs CMTI rating for applications with significant noise or rapid voltage transients. The wide operating temperature range makes it suitable for industrial and automotive-grade environments where thermal stability is critical for long-term reliability.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares the same core architecture as other variants like the ADUM3200BRZ but may differ in manufacturing lot specifications or performance tolerances associated with the EP designation. The series is widely used for replacing traditional optocouplers in modern digital communication interfaces.

Replacement Considerations

Direct pin-compatible substitutes include the ADUM3200BRZ and ADUM3200WARZ. Verify that the replacement variant meets the specific 25 Mbps data rate and 25 kV/µs CMTI requirements of the original design.
