ADUM142E0BRQZ

Digital Isolators Overview

The ADUM142E0BRQZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent channels with two unidirectional forward paths and two reverse paths. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical specifications include an insulation voltage of 3000 Vrms, a propagation delay of 15 ns, and a typical operating current of 11 mA. It features a common-mode transient immunity of 75 kV/µs and functions reliably across an industrial temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated digital channels using on-chip transformer-based magnetic coupling for high-speed signal transmission.
• Provides robust galvanic isolation with a rated insulation voltage of 3000 Vrms to protect sensitive circuitry.
• Delivers high common-mode transient immunity of 75 kV/µs to maintain signal integrity in noisy environments.
• Supports low-power operation with a typical supply current of 11 mA per side while maintaining fast propagation delays.

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise rejection
• Automotive electronic control units (ECUs) for reliable data transfer

Digital Isolators Procurement Notes

Verify the specific suffix '0' indicates the correct isolation rating and channel configuration for your design requirements. Confirm package compatibility with QSOP-16 footprints during layout. Check manufacturer documentation for updated lifecycle status as availability may vary. Ensure voltage levels match the 1.7 V to 5.5 V operational range before integration.

Digital Isolators Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact form factor. Compare against other ADUM142 variants if different insulation ratings or package types are needed. Consider the 150 Mb/s data rate limit for high-speed applications. Evaluate power consumption against system constraints given the 11 mA typical current draw.

Digital Isolators Part Context

This part belongs to the ADuM142E series of digital isolators from Analog Devices. It is designed for applications demanding high reliability and small footprint. The series leverages iCoupler technology to replace traditional optocouplers, offering improved performance and consistency. It is widely used in industries requiring strict safety isolation standards.

Digital Isolators Replacement Considerations

Check for direct substitutes like ADUM142E1BRQZ for similar functionality with potential pinout or rating differences. Verify cross-references with other quad-channel isolators if supply constraints exist. Ensure any replacement maintains the 3000 Vrms isolation and 150 Mb/s speed requirements.
