ADUM141D0BRQZ-RL7

Digital Isolators Overview

The ADUM141D0BRQZ-RL7 is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It operates with a supply voltage range of 1.7V to 5.5V and supports data rates up to 150Mbps. The device features an isolation voltage of 3000Vrms and a common mode transient immunity of 75kV/µs. It has a channel configuration of three forward and one reverse unidirectional path, housed in a 16-pin QSOP package.

Digital Isolators Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust noise immunity with a minimum common mode transient immunity rating of 75kV/µs across all channels.
• Supports flexible logic interface configurations with a specific arrangement of three forward and one reverse unidirectional channel.
• Operates reliably within an extended industrial temperature range from -40°C to +125°C.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral sensors.
• Medical equipment interfaces needing reliable signal separation and patient safety compliance.
• Power electronics control circuits isolating gate drivers from low-voltage logic controllers.
• Data acquisition systems protecting sensitive processing units from high-voltage noise environments.

Digital Isolators Procurement Notes

Verify the exact suffix QZ against the manufacturer's current datasheet to confirm pinout compatibility and insulation characteristics. Ensure the reel packaging matches your automated assembly requirements. Cross-reference the specific revision level to guarantee alignment with your design's electromagnetic interference constraints and regulatory standards.

Digital Isolators Selection Notes

Choose this component when a mixed-directional channel layout is required within a single isolated barrier. The 150Mbps data rate suits moderate-speed digital communication protocols. Consider the 16-pin QSOP footprint for space-constrained printed circuit board designs where surface-mount assembly is preferred over through-hole alternatives.

Digital Isolators Part Context

This part belongs to the ADuM141 series of quad-channel digital isolators. It represents Analog Devices' implementation of silicon-based magnetic isolation, offering an alternative to traditional optocouplers by providing superior speed, lower power consumption, and better consistency across manufacturing batches without degrading light-emitting diode components.

Digital Isolators Replacement Considerations

Direct substitutes include other ADuM141 variants with different channel directions or insulation ratings. Verify that any replacement maintains the 16-pin QSOP package dimensions and compatible supply voltage ranges to ensure mechanical and electrical interchangeability without redesigning the host circuit board.
