ADUM2400ARWZ-RL

Overview

The ADUM2400ARWZ-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 supports data rates up to 1 Mb/s. The device provides an isolation voltage of 5000 Vrms with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a propagation delay of 65 ns, rise/fall times of 3 ns, and a pulse width distortion of 1000 ns. It functions in temperatures from -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent bidirectional channels using monolithic air core transformer technology for signal isolation.
• Provides robust electromagnetic interference rejection through high common-mode transient immunity capabilities.
• Supports CMOS logic level translation between 3 V and 5 V domains without external components.

Applications

• Industrial automation systems requiring galvanic isolation for sensor interfaces
• Medical equipment needing reliable signal separation for patient safety compliance
• Power electronics control circuits for gate drive isolation

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status as required by project specifications. Check current availability as distribution may vary. Ensure the SOIC-16 footprint matches the PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are required in a compact surface-mount package. Consider the 1 Mb/s data rate limit for high-speed applications. Evaluate the 5000 Vrms isolation rating against system safety requirements. Compare power consumption figures if battery-operated designs are involved.

Part Context

This part belongs to the ADUM2400 series of quad-channel digital isolators. It shares the iCoupler architecture with related models like the ADUM2401. The series emphasizes low power consumption and high reliability for industrial environments. The ARWZ designation specifies the temperature grade and package type within the product line.

Replacement Considerations

The ADUM2401ARWZ-RL is a confirmed substitute offering identical pinout and functionality. Verify that the replacement meets all thermal and electrical specifications for the intended application environment.
