ADUM141D0BRWZ-RL

Digital Isolators Overview

The ADUM141D0BRWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a 3:1 input-to-output configuration. The device supports data rates up to 150 Mbps and offers an isolation voltage of 3750 Vrms. Key electrical parameters include a propagation delay of 13 ns, rise/fall times of 2.5 ns, and a common-mode transient immunity of 75 kV/µs. It operates on a supply voltage range of 1.7 V to 5.5 V, consumes 11.4 mA, and functions within a temperature range of -40°C to +125°C. Packaged in a 16-SOIC.

Digital Isolators Feature Summary

• Integrates four independent digital isolation 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.
• Supports flexible logic configurations with three input channels and one output channel per side.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfacing
• Isolated gate drive circuits for power electronics

Digital Isolators Procurement Notes

Verify the specific suffix 'D0' indicates the 3750 Vrms insulation rating and SOIC-16 package variant. Confirm that the '-RL' suffix denotes reel packaging options such as cut tape or Digi-Reel. Ensure compatibility with the required 1.7 V to 5.5 V supply voltage and check for moisture sensitivity handling requirements during assembly.

Digital Isolators Selection Notes

Select this component when high common-mode transient immunity and low propagation delay are critical. Compare against variants with lower insulation ratings if system voltage constraints allow. Consider the 16-SOIC footprint for PCB layout compatibility. Evaluate thermal dissipation needs given the 1.64 W power dissipation capability at maximum operating temperatures.

Digital Isolators Part Context

This part belongs to the ADuM141 series of robust quad digital isolators from Analog Devices. It complements other models like the ADUM141E0BRWZ-RL which may offer different insulation ratings or package types. The series is designed for applications demanding reliable signal integrity across isolation barriers in noisy environments.

Digital Isolators Replacement Considerations

Direct substitutes include ADUM141D0BRZ-RL7 and ADUM141D0BRWZ. Verify package compatibility and insulation voltage ratings before substitution.
