ADUM2402BRIZ-RL

Overview

The ADUM2402BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an isolation voltage of 5000 Vrms. The device supports bidirectional data transmission with a maximum data rate of 90 Mb/s. Key electrical characteristics include a typical propagation delay of 32 ns, rise and fall times of 3 ns, and a working supply current of 44 mA. It functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent channels for high-density signal isolation using proprietary iCoupler technology.
• Provides robust common-mode transient immunity to mitigate noise in electrically noisy environments.
• Supports bidirectional communication for flexible interface configurations.
• Operates on a single power supply rail without requiring isolated secondary supplies.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and field devices.
• Medical equipment interfaces needing high-voltage safety isolation.
• Power electronics gate drive circuits for inverters and motor drives.
• Automotive electronic control units (ECUs) demanding reliable signal integrity.

Procurement Notes

Verify the specific suffix 'BRIZ-RL' against official Analog Devices documentation to confirm package type, tape-and-reel quantity, and regional availability restrictions. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when high channel density and moderate speed are required alongside strong isolation capabilities. Compare propagation delay and power consumption against other iCoupler variants if lower latency or reduced current draw is critical for the specific application design constraints.

Part Context

This part belongs to the ADUM2402 series of quad-channel digital isolators. It shares the same functional architecture as the ADUM2402ARIZ-RL but may differ in specific performance parameters such as propagation delay or manufacturing lot specifications. It is distinct from the ADUM1402 series which offers different isolation ratings and channel configurations.
