ADUM1402ARW-RL

Overview

The ADUM1402ARW-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 1 Mbps and an isolation voltage of 2500 Vrms. The device operates on a supply voltage range of 2.7V to 5.5V, with a typical operating current of 44 mA. Key electrical parameters include a maximum propagation delay of 65 ns, typical rise/fall times of 3 ns, and a common-mode transient immunity of 25 kV/µs. It functions within a temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Implements iCoupler magnetic coupling technology for signal isolation without optical components
• Provides four independent unidirectional signal paths for general-purpose digital isolation
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments

Applications

• Industrial communication bus isolation
• Medical equipment signal isolation
• Power metering and energy monitoring systems

Procurement Notes

Verify the specific suffix RL indicates reel packaging configuration distinct from tube variants. Confirm RoHS compliance status and lead times through authorized distributors as this component may have limited availability or obsolescence status. Ensure the ordering part number matches the required tape-and-reel quantity specifications for production integration.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required at 1 Mbps speeds. Consider the 2500 Vrms isolation rating for safety-critical applications. Evaluate the SOIC-16 footprint against PCB space constraints. Compare power consumption characteristics against alternative isolators if low-power operation is a primary design constraint.

Part Context

This part belongs to the ADUM1402 series of quad-channel digital isolators from Analog Devices. It is part of the broader iCoupler family, which integrates transformer-based isolation on-chip. The series includes variants with different channel directions and packaging options, serving as a compact replacement for traditional optocouplers in modern interface designs.

Replacement Considerations

Public confirmed substitute part numbers include ADUM1402A.
