ADUM2400BRIZ-RL

Overview

The ADUM2400BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional data flow at speeds up to 90 Mb/s. The device provides an insulation voltage of 5000 Vrms and features a propagation delay of 50 ns with rise and fall times of 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC (W) format on a reel, it draws approximately 70 mA of operating current.

Feature Summary

• Provides four independent bidirectional channels for digital signal isolation using magnetic coupling technology.
• Supports high-speed data transmission rates up to 90 Mb/s with low propagation delay characteristics.
• Offers robust electrical isolation with a rated insulation voltage of 5000 Vrms for safety-critical applications.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for patient safety
• Power electronics control circuits demanding high common-mode transient immunity

Procurement Notes

Verify the specific suffix and package variant against official Analog Devices documentation before procurement. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure the component meets all required environmental and regulatory standards for the intended deployment environment.

Selection Notes

Select this component when four isolated channels are required within a single package to save board space. Consider the 5000 Vrms isolation rating for applications involving high-voltage separation. Evaluate the 90 Mb/s data rate capability against system timing requirements to ensure compatibility with existing communication protocols.

Part Context

This part belongs to the ADuM2400 series of quad-channel digital isolators manufactured by Analog Devices. It is designed to replace traditional optocouplers in modern designs, offering superior performance in speed, power consumption, and reliability. The series is widely used in industrial and medical sectors where robust signal integrity and isolation are paramount.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM family that may offer updated packaging or revised specifications. Verify that any substitute maintains the same 5000 Vrms isolation rating and channel count to ensure functional equivalence in existing circuit designs.
