ADUM3200BRZ

Overview

The ADUM3200BRZ 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 10 Mb/s. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a maximum propagation delay of 50 ns, typical rise and fall times of 2.5 ns, and a pulse width distortion of 3 ns. It functions in unidirectional mode with two channels and maintains performance across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS circuitry with monolithic transformers for signal transmission without external magnetics
• Provides enhanced system-level electrostatic discharge reliability compared to standard optical couplers
• Delivers bidirectional signal isolation through compact surface-mount packaging

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment interfaces needing reinforced insulation
• Power metering circuits for accurate signal separation

Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats vary between tube and reel configurations. Confirm current availability status directly with authorized distributors, as supply constraints may affect immediate fulfillment. Ensure compatibility with existing PCB footprints for SOIC-8 packages during integration planning.

Selection Notes

Select this component for applications demanding robust ESD protection and high common-mode noise rejection. Compare channel count and data rate requirements against similar models like the ADUM3201 if bidirectional communication is needed. Evaluate power consumption specifications relative to system thermal constraints.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It represents a transition from traditional optocouplers to silicon-based isolation solutions. The BRZ suffix indicates a lead-free RoHS-compliant variant housed in an 8-pin SOIC package suitable for automated assembly processes.

Replacement Considerations

The ADUM1200BRZ is listed as a parameter-equivalent substitute. Verify pinout compatibility and specific electrical tolerances before substitution.
