ADUM5412BRSZ-RL7

Overview

The ADUM5412BRSZ-RL7 is a quad-channel digital isolator from Analog Devices, featuring integrated isoPower isolated DC-to-DC converters. It provides four signal isolation channels with a data rate of 150 Mb/s and operates within a temperature range of -40°C to +105°C. The device offers an insulation voltage of 3750 Vrms and utilizes magnetic coupling for isolation. It has a propagation delay of 7.2 ns and draws 11 mA of operating supply current. Packaged in a 24-pin SSOP (SSOP-24) format, it supports unidirectional data transmission with high common-mode transient immunity.

Feature Summary

• Integrates isolated DC-to-DC converters to provide power across the isolation barrier
• Provides four independent signal isolation channels for complex system designs
• Utilizes magnetic coupling technology for robust signal transmission
• Supports high-speed data communication up to 150 Mb/s

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Inverter drives and motor control circuits
• Isolated ADC and DAC interfaces

Procurement Notes

Verify the specific suffix RL7 corresponds to the required reel packaging configuration before ordering. Confirm that the 24-SSOP package dimensions match your PCB footprint requirements. Ensure compatibility with the 3750 Vrms insulation rating for your safety standards. Check humidity sensitivity handling procedures as indicated in the datasheet. Validate that the 11 mA supply current fits your power budget constraints.

Selection Notes

Select this component when four isolated channels are needed alongside integrated power conversion. Consider the 150 Mb/s data rate for bandwidth requirements. Evaluate the 24-SSOP package size against available board space. Assess the need for unidirectional signal flow versus bidirectional alternatives. Verify thermal performance at the maximum operating temperature of 105°C.

Part Context

This part belongs to the ADuM541x family of quad-channel digital isolators with integrated isoPower technology. It is designed to replace traditional optocoupler solutions by offering higher reliability and lower power consumption. The series is widely used in applications demanding high-density isolation and precise timing characteristics.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADuM541x family if different channel configurations or voltage ratings are needed. Verify that any replacement maintains the same 24-SSOP package and electrical specifications.
