ADUM142D1BRWZ

Digital Isolators Overview

The ADUM142D1BRWZ is a general-purpose digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with a 2:2 input-output configuration and unidirectional signal transmission. The device supports data rates up to 150 Mbps and offers a minimum common-mode transient immunity of 75 kV/µs. It operates within a supply voltage range of 1.8 V to 5 V and functions across an extended temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC (0.295 inch width), it provides robust isolation for harsh environments.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for high-speed data transmission.
• Provides robust system protection against noisy, harsh, and unpredictable operating environments.
• Supports standard digital communication protocols including SPI interfaces.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Automotive electronic control units

Digital Isolators Procurement Notes

Verify the specific suffix BRWZ to confirm the 16-SOIC package and reel packaging format. Ensure compatibility with the required isolation voltage rating of 3750 Vrms for your circuit design. Confirm RoHS compliance status and moisture sensitivity level before assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Digital Isolators Selection Notes

Select this component when a quad-channel isolator with unidirectional logic is required. It is suitable for designs needing 3750 Vrms isolation strength and 150 Mbps data throughput. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate power consumption requirements as the device draws current based on data rate and supply voltage.

Digital Isolators Part Context

This part belongs to the ADUM142D series of robust iCoupler digital isolators. It shares architectural similarities with other members like the ADUM141 and ADUM140 but differs in channel configuration and isolation ratings. The series is designed for applications demanding high reliability and noise immunity in digital signal paths.

Digital Isolators Replacement Considerations

Direct substitutes include ADUM142D1BRZ for tube packaging or ADUM142E1BRWZ for higher isolation ratings. Verify pinout compatibility and electrical specifications before substitution.
