ADUM6423ABRNZ5

Overview

The ADUM6423ABRNZ5 is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It operates with a 1:3 data direction configuration and supports a maximum data rate of 100 Mb/s. The device provides 500 Vrms insulation voltage and functions within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 10 ns, pulse width distortion of 1 ns, and a typical operating supply current of 9 mA. It is housed in a SOIC-28 package and is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across the isolation barrier
• Provides high-speed data transmission with low latency and low electromagnetic interference characteristics
• Features a shutdown capability for power management and system control

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing galvanic isolation for safety compliance
• Automotive electronics utilizing high-speed data buses

Procurement Notes

Verify the specific suffix '5' indicates the reel packaging configuration when ordering. Confirm that the component meets RoHS standards as specified by the manufacturer. Ensure compatibility with the EVAL-ADUM6421A evaluation board if development support is required. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component for applications requiring four isolated channels with a 1:3 data direction ratio. It is suitable for designs needing integrated isolated power without external magnetics. Consider the SOIC-28 package size for PCB layout constraints. Verify that the 100 Mb/s data rate aligns with system timing requirements.

Part Context

This part belongs to the ADUM642x family of digital isolators, which utilize capacitive coupling technology for signal transmission. The family includes variants with different channel counts and data directions, such as the ADUM6420 and ADUM6424. These devices are designed to replace traditional optocouplers in high-performance applications.

Replacement Considerations

The ADUM6423ABRNZ3 is a similar quad-channel isolator but operates at 3V logic levels instead of 5V. Ensure voltage level compatibility when substituting. Other family members like the ADUM6420 offer different data direction configurations.
