ADUM2401BRIZ-RL

Overview

The ADUM2401BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features bidirectional data flow with a maximum data rate of 90 Mb/s and supports power supply voltages between 2.7 V and 5.5 V. The device provides 5000 Vrms insulation voltage and operates within a temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC format, it exhibits a propagation delay of 50 ns and typical supply currents of 70 mA per side.

Feature Summary

• Bidirectional communication capability for flexible signal routing
• Magnetic coupling isolation ensuring high reliability
• Integrated 3 V/5 V level translation for interface compatibility

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring

Procurement Notes

Verify the specific suffix 'ARIZ' or 'BRIZ' against design requirements, as these denote distinct performance characteristics such as data rate and directionality. Confirm package type (SOIC-16) and operating temperature range match system constraints. Check current availability status as distribution may be limited. Ensure RoHS compliance documentation is obtained prior to integration.

Selection Notes

Select this component when bidirectional isolation at speeds up to 90 Mb/s is required. Compare against unidirectional variants like the ADUM2401AR series if lower speed or one-way communication suffices. Evaluate power consumption differences, as higher-speed models typically draw more current. Ensure the 16-pin SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the ADUM2401 family of quad-channel digital isolators. It shares the same physical package and basic isolation architecture with other variants but differs in electrical specifications. The 'B' suffix indicates bidirectional functionality and higher data rates compared to 'A' series parts.

Replacement Considerations

ADUM2401CRIZ-RL offers similar bidirectional isolation but with different timing parameters. ADUM2401ARIZ-RL serves as a unidirectional alternative with lower data rates. Verify pinout compatibility and electrical specs before substitution.
