ADUM2401CRIZ-RL

Overview

The ADUM2401CRIZ-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 bidirectional data communication at rates up to 90 Mb/s. The device features four independent channels in a 16-pin SOIC package, providing an isolation voltage of 5000 Vrms. Key electrical specifications include a propagation delay of 32 ns, a common-mode transient immunity of 25 kV/µs, and a pulse width distortion of 11.1 ns maximum. It functions reliably across an industrial temperature range from -40°C to +105°C with a typical power consumption of 57 mA.

Feature Summary

• Bidirectional communication capability for flexible signal routing
• Magnetic coupling isolation technology ensuring high reliability
• Precision timing characteristics with low channel-to-channel skew
• Integrated 3 V/5 V level translation for system compatibility

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing high-voltage safety isolation
• Power metering applications with isolated communication interfaces
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the CRIZ designation corresponds to the bidirectional 90 Mbps variant rather than unidirectional or lower-speed alternatives. Ensure the SOIC-16 package width matches your PCB footprint requirements. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when bidirectional data transfer is required alongside high-speed performance up to 90 Mbps. The 5000 Vrms isolation rating suits applications demanding robust safety barriers. Consider the 57 mA power consumption against thermal constraints. Compare against unidirectional variants if directionality does not match design needs.

Part Context

This part belongs to the ADUM2401 series of quad-channel digital isolators. It shares the same physical package and basic isolation architecture with other variants like the ADUM2401ARIZ-RL but differs in data rate and directionality. The series is designed for general-purpose isolation in interface circuits where multiple channels are necessary.

Replacement Considerations
