ADUM3210TRZ-EP-RL7

Overview

The ADUM3210TRZ-EP-RL7 is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. 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 2500 Vrms insulation voltage and a common-mode transient immunity (CMTI) of 25 kV/µs. Packaged in an 8-pin SOIC, it functions unidirectionally with a typical propagation delay of 50 ns and power consumption of 7.6 mA per channel.

Feature Summary

• Enhanced system-level ESD reliability compared to standard industrial grade devices
• High common-mode transient immunity of 25 kV/µs for robust noise rejection
• Magnetic coupling isolation technology ensures long-term stability

Applications

• Industrial automation systems requiring enhanced ESD protection
• Medical equipment interfaces needing high reliability isolation
• Automotive electronics subject to harsh electrical environments

Procurement Notes

Verify the EP suffix indicates enhanced product specifications rather than standard commercial grade. Confirm package dimensions match SOIC-8 requirements. Check RoHS compliance status directly from the manufacturer datasheet. Ensure availability aligns with project timelines as specialized variants may have different supply chains.

Selection Notes

Select this component when standard digital isolators lack sufficient ESD robustness or CMTI performance. The EP variant offers improved durability for critical applications without changing the pinout or basic electrical interface of the ADUM3210 family. Validate thermal management needs for the SOIC-8 package under maximum operating conditions.

Part Context

This part belongs to the ADUM3210 series of dual-channel digital isolators. The EP designation signifies Enhanced Product characteristics, specifically targeting higher reliability standards. It shares the same functional architecture as the standard ADUM3210 but undergoes stricter screening and material controls for demanding environments.

Replacement Considerations

Direct substitutes include the standard ADUM3210TRZ-RL7 if ESD enhancements are not required. Verify that any replacement maintains the 25 kV/µs CMTI specification if noise immunity is critical. Cross-reference pinouts to ensure compatibility with existing PCB layouts.
