ADUM6401CRIZ

Overview

The ADUM6401CRIZ is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC/DC converter. It provides high-speed data transmission at 25 Mb/s with a propagation delay of 60 ns. The device supports unidirectional signal isolation with a maximum insulation voltage of 5000 Vrms and operates within a supply voltage range of 3 V to 5.5 V. Designed for robust performance, it offers a common-mode transient immunity of 25 kV/µs and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates an isolated DC/DC converter to eliminate the need for external power supplies on the isolation barrier
• Provides magnetic coupling-based isolation for reliable signal transmission across electrical boundaries
• Features high common-mode transient immunity to maintain signal integrity in noisy environments

Applications

• Industrial automation systems requiring galvanic isolation between control and field devices
• Medical equipment needing safe separation of patient-connected circuits from mains-powered components
• Power electronics interfaces for monitoring and controlling high-voltage switching elements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt to ensure solder joint reliability. Check datasheet revisions for any process change notices that may affect pinout or electrical characteristics. Ensure storage conditions comply with moisture sensitivity levels specified in the manufacturing documentation.

Selection Notes

Select this component when a single-chip solution for both data isolation and isolated power generation is required. Consider the 16-SOIC package dimensions for PCB layout constraints. Evaluate the 25 Mb/s data rate against system timing requirements. Verify that the 5000 Vrms insulation rating meets the specific safety standards applicable to the target application environment.

Part Context

This part belongs to the ADUM640x series of digital isolators, which are designed for general-purpose applications requiring high reliability. The 'C' suffix indicates commercial temperature range operation, while 'RIZ' denotes the specific reel packaging configuration. These devices are widely used in interface ICs where space efficiency and power consumption are critical design factors.

Replacement Considerations

Cross-reference with ADUM6400CRIZ or ADUM6402CRIZ for similar specifications. Verify pin compatibility and functional equivalence before substitution. Ensure that any alternative component meets the same insulation voltage and data rate requirements.
