ADUM2400ARIZ

Overview

The ADUM2400ARIZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional communication at data rates up to 90 Mbps (NRZ). The device provides an insulation voltage of 5000 Vrms and functions reliably across an operating temperature range of -40°C to +105°C. Key timing specifications include a propagation delay of 100 ns, rise/fall times of 3 ns, and pulse width distortion of 2 ns maximum. It is housed in a 16-lead SOIC package.

Feature Summary

• Integrates four independent isolation channels using iCoupler magnetic coupling technology for high-speed signal transmission.
• Supports bidirectional communication with automatic 3 V/5 V level translation capabilities.
• Delivers precise timing characteristics including matched channel-to-channel delays and minimal pulse width distortion.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripherals.
• Medical equipment interfaces needing high insulation voltage and safety compliance.
• Power electronics control circuits involving isolated gate driving or feedback loops.

Procurement Notes

Verify the specific suffix 'ARIZ' to confirm the industrial temperature grade (-40°C to +105°C) and SOIC-16 package variant. Ensure compatibility with the required 2.7 V to 5.5 V supply rails. Confirm that the 90 Mbps data rate meets system bandwidth requirements. Check for RoHS compliance status as indicated in official documentation before finalizing procurement orders.

Selection Notes

Select this component when four isolated digital channels are required in a compact footprint. It is suitable for applications demanding high common-mode transient immunity and low power consumption compared to optical isolators. Consider the 5000 Vrms insulation rating for safety-critical designs. Evaluate the 100 ns propagation delay against system timing constraints to ensure signal integrity is maintained.

Part Context

This part belongs to the ADuM2400 series of quad-channel digital isolators from Analog Devices. It shares the same core iCoupler architecture as related models like the ADUM2401 and ADUM2402, differing primarily in pinout configurations and specific channel assignments. The series is designed to replace traditional optocouplers in space-constrained, high-reliability applications.

Replacement Considerations

Direct replacements may include ADUM2401ARIZ or ADUM2402ARIZ, provided pinout compatibility is verified. Cross-reference datasheets to ensure identical insulation ratings and data rate specifications. Verify that alternative parts support the same 3 V/5 V logic levels and SOIC-16 package dimensions.
