ADUM5412BRSZ

Overview

The ADUM5412BRSZ is a quad-channel digital isolator featuring integrated isoPower isolated DC-to-DC converters. It provides four signal isolation channels with a data rate of 150 Mbps and a propagation delay of 7.2 ns. The device offers an insulation voltage of 3750 Vrms and a common-mode transient immunity of 75 kV/µs. Operating on a supply voltage range of 1.7V to 5.5V, it draws 11 mA of operating power supply current. The component is housed in a 24-SSOP package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates isolated DC-to-DC converters for independent side power supplies
• Provides magnetic coupling-based galvanic isolation for signal channels
• Supports unidirectional data transmission across four channels

Applications

• Industrial automation systems requiring high noise immunity
• Medical equipment needing secure patient isolation
• Inverter motor control circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the SSOP-24 package dimensions match your PCB footprint requirements. Ensure the 105°C maximum operating temperature aligns with your thermal design constraints. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when four isolated channels are needed alongside integrated power conversion. It eliminates external isolated power supplies, reducing board space. Consider the 150 Mbps speed limit for signal integrity. Verify that the 24-SSOP package fits within your assembly capabilities and clearance requirements.

Part Context

This part belongs to the ADuM541x family of quad-channel digital isolators. These devices utilize iCoupler technology for magnetic signal transmission. The series is designed to replace traditional optocouplers in applications demanding higher reliability and lower power consumption while maintaining robust isolation performance.

Replacement Considerations

The ADUM5410 and ADUM5411 are related parts within the same family. They share similar features but may differ in channel configuration or power output specifications. Verify functional compatibility before substitution.
