ADUM6201CRIZ-RL

Overview

The ADUM6201CRIZ-RL is a dual-channel digital isolator from Analog Devices, featuring integrated DC/DC converters for isolated power delivery. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 5000 Vrms and an 8mm creepage distance. The device supports unidirectional data transmission at a maximum data rate of 25 Mb/s. It operates within a supply voltage range of 3 V to 5.5 V and exhibits a typical propagation delay of 60 ns. The component is housed in a 16-pin SOIC package and is designed for operation across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates on-chip DC/DC converters to provide isolated power supplies for both sides of the isolation barrier, eliminating the need for external isolated power sources.
• Employs iCoupler magnetic coupling technology to achieve high-voltage isolation without the limitations associated with optical or capacitive isolation methods.
• Offers bidirectional signal integrity through unidirectional channel configuration with low skew and jitter characteristics suitable for high-speed digital communication.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensor interfaces.
• Medical equipment needing reliable isolation for patient-connected circuits and safety compliance.
• Power electronics monitoring where high common-mode transient immunity is required for accurate signal acquisition.

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing components. Confirm that the CRIZ designation corresponds to the industrial temperature grade and SOIC-16 package variant. Ensure compatibility with existing board layouts regarding pinout and thermal requirements. Check current availability status as distribution may be limited due to supply constraints.

Selection Notes

Select this component when dual-channel isolation with integrated power is necessary to simplify system design. Consider the 25 Mb/s data rate limit for bandwidth requirements. Evaluate the 5000 Vrms isolation rating against system safety standards. Compare power consumption of the internal DC/DC converter against external solutions for efficiency optimization.

Part Context

This part belongs to the ADuM620x series of IsoPower digital isolators. It shares architectural similarities with other members like the ADUM6200 and ADUM6202 but differs in channel count and specific electrical characteristics. The series is designed for applications demanding robust isolation in compact surface-mount packages.

Replacement Considerations

The ADUM6201CRWZ is documented as a parameter-equivalent alternative. Verify package differences and availability before substitution. Other family members may require circuit adjustments due to varying channel counts or power specifications.
