ADUM6400CRIZ

Overview

The ADUM6400CRIZ is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC/DC converter. It provides four unidirectional signal channels with a data rate of 25 Mb/s and a propagation delay of 60 ns. The device offers 5000 Vrms isolation voltage and operates within a supply voltage range of 3 V to 5.5 V. It supports regulated 3.3 V or 5 V outputs up to 400 mW. Housed in a 16-SOIC package, it functions across temperatures from -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery
• Provides four unidirectional signal isolation channels
• Utilizes iCoupler magnetic coupling technology for high reliability

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation
• Power metering and energy management circuits

Procurement Notes

Verify the specific suffix (e.g., CRIZ) against the official datasheet to confirm pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements for your region. Confirm availability status as distribution may vary. Validate that the SOIC-16 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. It is suitable for applications demanding 5000 Vrms isolation with unidirectional data flow. Consider the 25 Mb/s data rate limit and 400 mW power output capability during system design. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the ADuM6400 family of digital isolators. It combines four isolated logic channels with an integrated isolated DC/DC converter. The series utilizes iCoupler technology, which replaces traditional transformers with on-chip microtransformers. This integration reduces board space and simplifies design compared to discrete isolation solutions.

Replacement Considerations

Check for direct substitutes within the ADuM64xx series. Verify pin compatibility and electrical specifications such as data rate and isolation voltage. Ensure any replacement maintains the same package type and thermal performance characteristics.
