ADUM151N1BRZ-RL7

Digital Isolators Overview

The ADUM151N1BRZ-RL7 is a robust five-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 4/1 channel configuration with unidirectional data flow. Key electrical parameters include a data rate of 150 Mb/s, isolation voltage of 3000 Vrms, and common-mode transient immunity of 75 kV/µs. The device operates on a single supply voltage ranging from 1.7V to 5.5V, with a typical operating current of 15 mA per side. Propagation delay is specified at 7.2 ns. It is housed in a 16-lead SOIC package and supports an operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates five independent digital channels using proprietary iCoupler magnetic coupling technology for signal isolation.
• Provides high common-mode transient immunity to reject noise in electrically noisy environments.
• Supports unidirectional data transmission with a single power supply domain on each side of the isolation barrier.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment interfaces needing reliable signal separation across safety barriers
• Power electronics control circuits isolating gate drivers from logic controllers

Digital Isolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to soldering. Ensure storage conditions adhere to humidity restrictions to prevent package damage. Validate that the reel packaging matches specific handling requirements for surface mount assembly processes.

Digital Isolators Selection Notes

Select this component when five isolated channels are required within a single package footprint. Consider the 150 Mbps data rate capability against system timing requirements. Evaluate the 3000 Vrms isolation rating against regulatory safety standards applicable to the target application environment. Compare power consumption characteristics against alternative isolator technologies for efficiency optimization.

Digital Isolators Part Context

This part belongs to the ADUM151N series of digital isolators. It shares architectural similarities with other iCoupler devices but offers a specific 5-channel configuration. The suffix RL7 indicates tape and reel packaging for automated assembly. It complements Analog Devices' portfolio of interface solutions designed for high-reliability industrial and medical applications.

Digital Isolators Replacement Considerations

The ADUM151N1BRZ is the non-reel variant of this component. Verify pinout compatibility if substituting with other 16-lead SOIC isolators. Cross-reference datasheets for propagation delay and isolation voltage specifications to ensure functional equivalence in existing designs.
