ADUM2401ARIZ-RL

Overview

The ADUM2401ARIZ-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 data rates up to 1 Mb/s. The device provides an insulation voltage of 5000 Vrms and features unidirectional channel polarity. Key timing parameters include a propagation delay of 65 ns, with rise and fall times of 3 ns each. It functions reliably across an extended temperature range from -40°C to +105°C. Packaged in a 16-pin SOIC format, it offers low power consumption with operating currents of 1.2 mA and 1.8 mA.

Feature Summary

• Quad-channel architecture enabling simultaneous isolation of four independent digital signals
• Magnetic coupling isolation mechanism providing galvanic separation between circuits
• High insulation voltage rating suitable for demanding safety applications
• Precision timing characteristics ensuring minimal pulse width distortion

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage safety compliance
• Power electronics interfaces for gate drive isolation
• Data acquisition systems with noisy ground environments

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation before integration. 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 precisely.

Selection Notes

Select this component when four isolated channels are required within a single package. Consider the 1 Mb/s data rate limit against system throughput needs. Evaluate the 5000 Vrms insulation rating against circuit isolation requirements. Compare power consumption figures against battery-operated or thermally constrained designs.

Part Context

This part belongs to the ADUM2401 series of digital isolators manufactured by Analog Devices. It shares the same functional core with variants like ADUM2401ARIZ but differs in packaging configuration. The series is designed for general-purpose isolation tasks where size and performance balance is critical.

Replacement Considerations

Direct substitutes include other ADUM2401 variants such as ADUM2401ARIZ or ADUM2401CRIZ, provided the package and temperature grade match. Cross-referencing pinouts and electrical specifications is essential before substitution.
