Overview
The ADUM6420ABRNZ5-RL is a four-channel digital isolator from Analog Devices, featuring an integrated isoPower DC/DC converter. It operates at a data rate of 100 Mb/s with a propagation delay of 10 ns and supports a 5V supply voltage. The device provides 5kVrms insulation isolation and utilizes magnetic coupling technology. Packaged in a 28-pin SOIC-W, it offers high common-mode transient immunity for reliable signal transmission across isolated boundaries.
Feature Summary
- Integrates a low EMI switching regulator to generate the isolated power supply
- Provides galvanic isolation between input and output circuits via magnetic coupling
- Supports unidirectional data transmission across four independent channels
Applications
- Industrial automation control systems requiring robust signal isolation
- Medical equipment needing high-voltage safety compliance
- Power electronics monitoring interfaces
- Data acquisition systems with mixed-signal grounding requirements
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for updated electrical characteristics. Ensure storage conditions meet humidity sensitivity standards before assembly.
Selection Notes
Choose this component when four isolated channels with integrated power generation are required. Consider the 100 Mb/s speed and 5kV isolation rating against system noise levels. Evaluate thermal performance within the SOIC-28 package constraints. Compare against alternatives if bidirectional communication or different voltage levels are needed.
Part Context
This part belongs to the ADUM64xx series of digital isolators designed for high-reliability applications. It combines signal isolation with power delivery in a single package, reducing board space compared to discrete solutions. The series targets industries demanding strict safety regulations and electromagnetic compatibility.
Replacement Considerations
ADUM6423ABRNZ5-RL: Offers similar isolation but with different channel configuration (1:3). ADUM6421ABRNZ5-RL: Provides bidirectional capability instead of unidirectional. Verify pinout compatibility and electrical parameters before substitution.
