ADUM142E0BRQZ-RL7

Digital Isolators Overview

The ADUM142E0BRQZ-RL7 is a robust quad digital isolator from Analog Devices, featuring four independent channels with a 2:2 configuration. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 3000 Vrms. The device supports data rates up to 150 Mb/s and operates within a supply voltage range of 1.7 V to 5.5 V. Key performance metrics include a propagation delay of 15 ns and a typical operating current of 11 mA. It is housed in a QSOP-16 package and functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation via proprietary magnetic coupling technology for signal integrity
• Features unidirectional channel polarity suitable for one-way data transmission applications
• Offers high common-mode transient immunity to maintain performance in noisy environments

Digital Isolators Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing reinforced isolation for patient safety
• Power electronics control circuits with high-voltage noise rejection

Digital Isolators Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as supply may be limited or restricted. Ensure compatibility with QSOP-16 footprints during PCB layout. Check RoHS compliance documentation for regulatory adherence. Validate that the 3000 Vrms rating meets system isolation requirements.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for quad-channel designs. Compare against ADUM142E1 variants if bidirectional communication is needed instead. Consider the 15 ns propagation delay for timing-sensitive applications. Evaluate power consumption at 11 mA against battery-operated constraints. Ensure the QSOP-16 package fits the available board space.
