ADUM6423ABRNZ3

Overview

The ADUM6423ABRNZ3 is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides four unidirectional data channels with a maximum data rate of 100 Mb/s and a common mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 3 V to 5.5 V and offers an insulation voltage of 5000 Vrms via magnetic coupling. Key electrical parameters include a propagation delay of 10 ns (typical) and pulse width distortion of 1 ns. It functions within a temperature range of -40°C to +125°C and is housed in a 28-SOIC package.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across the isolation barrier.
• Provides four independent unidirectional signal paths for high-speed data transmission.
• Utilizes magnetic coupling technology to achieve high common mode transient immunity.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment with strict safety isolation standards
• High-voltage measurement instrumentation

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement.
