ADUM3200TRZ-EP

Overview

The ADUM3200TRZ-EP is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides two independent isolation channels with unidirectional signal transmission. The device operates on supply voltages between 3 V and 5.5 V. Key electrical parameters include a data rate of 25 Mb/s, an insulation voltage of 2500 Vrms, and a common-mode transient immunity (CMTI) of 25 kV/µs. Propagation delay is typically 45 ns, with rise and fall times of 2.5 ns. It functions within a temperature range of -40°C to +85°C and is housed in an 8-SOIC package.

Feature Summary

• Dual-channel unidirectional digital isolation using proprietary magnetic coupling technology
• High common-mode transient immunity for reliable operation in noisy environments
• Enhanced system-level ESD reliability compared to standard industrial isolators
• Operates with 3.3 V or 5 V supply voltages on either side of the isolation barrier

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing enhanced safety isolation
• Power metering applications with high-voltage interfaces
• Inverter drives and motor control circuits

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the EP suffix indicates military-grade qualification standards. Check current availability as supply may be restricted. Ensure storage conditions comply with moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this component when dual-channel unidirectional isolation is required. Compare propagation delay and CMTI specifications against application needs. Consider the 8-SOIC package constraints for PCB layout. Evaluate power consumption relative to other iCoupler variants if low-power operation is critical.

Part Context

This part belongs to the ADUM3200 series of digital isolators. It shares the iCoupler architecture with other models in the family but offers specific performance characteristics tailored for robust industrial and medical applications. The EP designation signifies extended performance or military-grade screening.

Replacement Considerations

The ADUM1200BRZ is listed as a parameter-equivalent alternative. Verify channel configuration and data rate compatibility before substitution. Ensure thermal and mechanical specifications match the existing design constraints.
