ADUM251N0BRIZ-RL

Overview

The ADUM251N0BRIZ-RL is a robust digital isolator from Analog Devices, featuring five channels with a 4/1 input/output configuration. It utilizes magnetic coupling technology to provide an insulation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 1.7 V to 5.5 V, drawing a typical operating current of 13.7 mA. Key electrical parameters include a propagation delay of 7.2 ns, a pulse width of 6.6 ns, and a common mode transient immunity of 75 kV/µs. It is housed in a 16-SOIC package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via magnetic coupling technology for signal integrity
• Supports high-speed data transmission at rates up to 150 Mbps
• Features unidirectional channel architecture for simplified circuit design
• Ensures system safety with robust 5000 Vrms insulation capability

Applications

• Industrial automation control systems requiring isolated communication
• Medical equipment needing patient isolation barriers
• Power electronics monitoring and gate drive circuits
• Test and measurement instrumentation interfaces

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the N0 designation corresponds to the 4/1 channel configuration rather than other variants like N1. Ensure compatibility with 16-SOIC footprints during PCB layout. Check for RoHS compliance documentation if required by project specifications. Validate that the 5000 Vrms rating meets the isolation requirements of the target application environment.

Selection Notes

Select this component when a unidirectional isolator with four inputs and one output is required. Consider the 150 Mbps data rate limit for bandwidth needs. Evaluate the 13.7 mA supply current against power constraints. The 75 kV/µs CMTI rating is critical for noisy environments. Compare the 16-SOIC package size against available board space. Verify the -40°C to +125°C operating range suits the environmental conditions.

Part Context

This part belongs to the ADUM251N series of digital isolators from Analog Devices. It shares the core magnetic coupling technology and SOIC-16 form factor with related models such as the ADUM251N1BRIZ-RL. The primary distinction lies in the channel configuration, where this variant offers a 4/1 split compared to other configurations in the family. It serves as a general-purpose solution for multi-channel isolation needs.

Replacement Considerations

Direct substitutes within the same family include the ADUM251N1BRIZ-RL, though it features a different channel arrangement. Cross-family replacements may require verification of pinout compatibility and electrical parameter alignment. Ensure any alternative maintains the 5000 Vrms isolation rating and 150 Mbps speed requirement.
