ADUM2402BRWZ-RL

Overview

The ADUM2402BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an isolation voltage of 5000 Vrms. The device supports a data rate of 10 Mbps with a maximum propagation delay of 50 ns and a common-mode transient immunity (CMTI) of 25 kV/µs. Packaged in a 16-SOIC surface-mount format, it functions unidirectionally across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent isolation channels using monolithic air core transformer technology for robust signal transmission.
• Eliminates design difficulties associated with optocouplers by avoiding LEDs and photodiodes, ensuring stable performance without current transfer ratio uncertainties.
• Features a patented refresh mechanism that maintains DC correctness during power-up, power-down, or absence of input logic transitions.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power management circuit monitoring
• General-purpose digital isolation in noisy environments

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notification. Ensure the component matches the required channel configuration and data rate for the target application before procurement.

Selection Notes

Select this component when high-speed 10 Mbps isolation is required alongside low power consumption. Compare against the ADUM2402ARWZ variant if a lower 1 Mbps data rate suffices for the application. Consider the ADUM2401 series if bidirectional communication capabilities are necessary instead of the unidirectional architecture provided here.

Part Context

This part belongs to the ADuM2400/ADuM2401/ADuM2402 family of quad-channel digital isolators. These devices leverage CMOS technology combined with iCoupler isolation to offer superior performance compared to traditional optocouplers. The family provides various channel configurations and data rates to suit different system isolation needs.

Replacement Considerations

Publicly confirmed substitute part numbers include ADUM2402ARWZ and ADUM2402BRIZ. Verify compatibility regarding data rate differences and packaging formats before substitution.
