ADUM231E1BRIZ-RL

Overview

The ADUM231E1BRIZ-RL is a robust digital isolator from Analog Devices, featuring three independent channels with unidirectional data flow. It utilizes magnetic coupling technology to provide electrical isolation between circuit sections. The device supports a data rate of 150 Mb/s and offers an insulation voltage of 5000 Vrms. Key performance metrics include a propagation delay of 7.2 ns and a common mode transient immunity of 75 kV/µs. It operates within a temperature range of -40°C to +125°C and draws 8.8 mA of supply current. Packaged in a 16-pin SOIC format.

Feature Summary

• Provides galvanic isolation via magnetic coupling technology for signal transmission across isolated boundaries.
• Features high common mode transient immunity to maintain signal integrity in noisy environments.
• Supports unidirectional data transfer with low propagation delay for precise timing applications.

Applications

• Industrial process control systems requiring robust signal isolation
• Medical equipment needing high-voltage isolation safety compliance
• Power electronics monitoring and gate drive circuits

Procurement Notes

Verify the specific suffix E1 against official Analog Devices documentation to confirm the exact isolation rating and package variant. Ensure compatibility with system voltage levels and thermal requirements. Check for moisture sensitivity labeling and handling instructions prior to assembly. Confirm availability status through authorized distributors as supply may be restricted.

Selection Notes

Select this component when high-speed unidirectional isolation is required with minimal propagation delay. The 150 Mb/s data rate suits standard communication protocols. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate the 5000 Vrms isolation barrier against system safety standards. Compare power consumption against other iCoupler series options if battery life is critical.

Part Context

This part belongs to the ADUM231 family of digital isolators. It shares architectural similarities with variants like the ADUM231D1BRIZ-RL but differs in specific electrical characteristics or qualification levels defined by the suffix. The series leverages Analog Devices' proprietary iCoupler technology for compact, reliable isolation solutions.
