ADUM141E1BRQZ

Digital Isolators Overview

The ADUM141E1BRQZ is a general-purpose digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with a 3:1 input-to-output configuration (three forward, one reverse). The device supports data rates up to 150 Mbps and offers a common-mode transient immunity of 75 kV/µs. It operates within a supply voltage range of 1.7 V to 5.5 V and is qualified under AEC-Q100 standards for automotive applications. The unit provides an isolation voltage of 3000 Vrms and functions reliably across an extended temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust protection against common-mode transients with a specified immunity rating of 75 kV/µs.
• Features unidirectional channel polarity with a three-channel forward and one-channel reverse configuration.
• Includes AEC-Q100 qualification ensuring reliability for demanding automotive electronic environments.

Digital Isolators Applications

• Automotive engine control units requiring isolated sensor interfaces
• Industrial motor drive gate driver circuits
• Medical equipment signal isolation barriers
• Power supply feedback loop isolation

Digital Isolators Procurement Notes

Verify the specific suffix QZ indicates the SSOP-16 package variant when sourcing. Confirm AEC-Q100 automotive qualification status is required for your application environment. Check current availability as distribution may be limited or restricted in certain regions. Ensure compatibility with 1.7 V to 5.5 V logic levels before integration. Validate that the 3000 Vrms isolation rating meets your system safety requirements.

Digital Isolators Selection Notes

Select this component when high common-mode transient immunity is critical for noise rejection in electrically noisy environments. The 150 Mbps data rate suits moderate-speed digital communication needs. Consider the 3:1 channel split if asymmetric signal flow is desired. The wide operating temperature range allows use in harsh conditions without derating. Verify pinout compatibility if replacing legacy isolators in existing designs.

Digital Isolators Part Context

This part belongs to the ADUM141ES series of quad-channel digital isolators. It shares architectural similarities with other iCoupler devices but distinguishes itself through automotive qualification and specific package options. The E1 suffix typically denotes the 3000 Vrms insulation level compared to higher ratings in other variants. It complements Analog Devices' broader portfolio of interface and isolation solutions for industrial and automotive sectors.

Digital Isolators Replacement Considerations

Direct substitutes include ADUM141E1BRWZ for SOIC-16 packaging with identical electrical characteristics. ADUM141E0BRQZ serves as a lower insulation voltage alternative at 1500 Vrms. Cross-reference pinouts and thermal performance when transitioning between SSOP and SOIC packages. Verify that the replacement maintains the same 75 kV/µs CMTI rating for equivalent noise immunity.
