ADUM6412BRSZ-RL7

Overview

The ADUM6412BRSZ-RL7 is a four-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for robust isolation. It provides unidirectional signal transmission with a data rate of 150 Mb/s and a propagation delay of 15 ns. The device offers 3750 Vrms insulation voltage and operates within a temperature range of -40°C to +105°C. Packaged in a 24-lead SSOP, it supports power supply voltages up to 5.5V.

Feature Summary

• Integrates a high-efficiency DC/DC converter to provide isolated power without external components
• Utilizes iCoupler magnetic coupling technology for reliable signal transmission across isolation barriers
• Supports high-speed data communication with a 150 Mb/s data rate per channel

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits
• Inverter and motor drive applications

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the BRSZ designation matches the required SSOP-24 package width and lead form. Ensure the internal DC/DC converter requirements align with your system's power budget and layout constraints before finalizing procurement.

Selection Notes

Select this component when four isolated channels are needed alongside an integrated isolated power source. It is suitable for designs requiring 3750 Vrms basic or reinforced isolation ratings. Consider the 150 Mb/s speed limit and 15 ns propagation delay for timing-sensitive applications compared to lower-speed alternatives.

Part Context

This part belongs to the ADUM64xx series of digital isolators. It shares the same core isolation architecture as other members but is configured specifically for four channels with two-way power transfer capabilities via the internal converter. It complements single-channel or dual-channel variants in the product family.

Replacement Considerations

Public confirmed substitute part numbers: ADUM6412ARZ-RL7 (Tube packaging equivalent). Verify pinout compatibility and thermal performance differences between tube and reel packaging variants.
