ADUM2400CRIZ-RL

Overview

The ADUM2400CRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for galvanic isolation. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional data transmission at rates up to 90 Mb/s. The device features a propagation delay of 32 ns with rise and fall times of 3 ns. It provides an insulation voltage of 5000 Vrms and maintains common-mode transient immunity characteristics suitable for noisy environments. Packaged in a 16-pin SOIC format, it functions reliably across temperatures from -40°C to +105°C.

Feature Summary

• Provides four independent bidirectional channels for digital signal isolation using magnetic coupling technology.
• Supports high-speed data transmission with a maximum rate of 90 Mb/s per channel.
• Ensures robust electrical safety with an insulation voltage rating of 5000 Vrms.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for patient safety
• Power electronics control circuits involving high-voltage switching

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation as required by regional regulations. Check current availability as distribution may be limited or subject to factory order constraints. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when four isolated channels are necessary for bidirectional data transfer. Consider the 90 Mb/s speed limit against your system's timing requirements. Evaluate the 5000 Vrms insulation capability against your circuit's isolation voltage needs. Compare power consumption figures if battery life is a critical design constraint.

Part Context

This part belongs to the ADuM2400 series of quad-channel digital isolators. It shares the same core architecture and pinout with variants like the ADUM2402, differing primarily in internal configuration or specific performance metrics. The series represents Analog Devices' solution for replacing traditional optocouplers in modern digital isolation applications.

Replacement Considerations

The ADUM2402CRIZ-RL is a confirmed substitute within the same family, offering similar isolation characteristics. Verify functional equivalence regarding channel count and data rates before swapping components in existing designs.
