ADUM1311BRWZ-RL

Digital Isolators Overview

The ADUM1311BRWZ-RL is a triple-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 supports data rates up to 10 Mb/s. The device features a propagation delay of 50 ns and a common-mode transient immunity of 25 kV/µs. It provides an isolation voltage of 3750 Vrms and functions reliably across an operating temperature range of -40°C to +105°C. Packaged in a 16-SOIC surface-mount format, it offers unidirectional signal transmission with low power consumption.

Digital Isolators Feature Summary

• Integrates three independent digital channels using monolithic air core transformer technology for robust signal isolation.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports bidirectional logic configuration with unidirectional channel polarity for flexible interface design.

Digital Isolators Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal processing interfaces
• Power electronics gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the BRWZ variant corresponds to the 10 Mb/s speed grade rather than the ARWZ 1 Mb/s version. Ensure compatibility with 16-SOIC footprint requirements during PCB layout. Check RoHS compliance status against current regulatory standards for your target market before finalizing procurement.

Digital Isolators Selection Notes

Select this component when three isolated channels are required at 10 Mb/s speeds. Compare against ADUM1311ARWZ-RL if lower data rates suffice for cost optimization. Consider the 16-SOIC package constraints for board space. Evaluate the 3750 Vrms isolation rating against system safety requirements. Assess power budget needs given the specified operating current ranges.

Digital Isolators Part Context

This part belongs to the ADUM1311 series of triple-channel digital isolators. It represents Analog Devices' implementation of iCoupler technology, which replaces traditional optocouplers with on-chip transformers. The series includes variants with different speed grades and temperature ratings, all sharing the same fundamental isolation architecture and pinout structure.

Digital Isolators Replacement Considerations

The ADUM1311ARWZ-RL serves as a slower alternative with 1 Mb/s data rate capability. Cross-reference pinouts and isolation voltages when substituting with other manufacturers' triple-channel isolators. Verify that any replacement maintains the 16-SOIC package dimensions and thermal characteristics.
