ADUM141E0BRQZ

Digital Isolators Overview

The ADUM141E0BRQZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. The device provides 3000 Vrms isolation voltage and features a common-mode transient immunity (CMTI) of 75 kV/µs. Key electrical parameters include a propagation delay of 15 ns, rise/fall times of 2.5 ns, and an operating supply current of 11.4 mA. It functions reliably across a temperature range of -40°C to +125°C and is housed in a 16-lead SSOP package.

Digital Isolators Feature Summary

• Integrates four independent digital channels for signal isolation using on-chip transformer technology
• Provides robust 3000 Vrms insulation barrier with high common-mode transient immunity
• Supports unidirectional data transmission with low propagation delay and jitter
• Operates from a single power supply ranging from 1.7 V to 5.5 V

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering and energy management circuits
• Inverter control and motor drive interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'QZ' confirms the 16-lead SSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure ESD handling protocols are followed during storage and assembly due to moisture sensitivity classification. Cross-reference pinouts with the latest datasheet revision to avoid integration errors.

Digital Isolators Selection Notes

Select this component when four isolated channels are required in a compact footprint. The 1.7 V to 5.5 V supply range accommodates various logic families. Consider the 150 Mb/s data rate limit for high-speed applications. The SSOP package suits space-constrained designs compared to wider SOIC alternatives. Evaluate thermal dissipation requirements based on the 11.4 mA typical supply current.

Digital Isolators Part Context

This part belongs to the ADUM141ES series of general-purpose digital isolators. It represents Analog Devices' implementation of iCoupler technology, which replaces traditional optocouplers with silicon-based magnetic isolation. The series offers improved performance metrics including lower power consumption and higher reliability compared to legacy isolation technologies.

Digital Isolators Replacement Considerations

The ADUM141E1BRZ-RL7 serves as a functional substitute with identical electrical specifications but utilizes a 16-lead SOIC package instead of SSOP. Verify mechanical fitment before substitution. Other ADUM141 variants may differ in channel count or package type.
