ADUM1412BRWZ-RL

Overview

The ADUM1412BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features four independent isolation channels with unidirectional signal transmission. The device operates within a supply voltage range of 2.7 V to 5.5 V on both sides. Key electrical parameters include a data rate of 10 Mbps, an insulation voltage of 3750 Vrms, and a typical propagation delay of 50 ns. It supports a maximum pulse width distortion of 5 ns and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates monolithic air core transformer technology for high-speed digital isolation without optical components
• Provides four independent bidirectional or unidirectional channels in a single package
• Includes patented refresh feature to ensure DC correctness during power-up/down conditions
• Enables voltage translation functionality across the isolation barrier

Applications

• Industrial communication interfaces requiring galvanic isolation
• Medical equipment signal isolation
• Power management systems with isolated control loops
• Automotive electronics data bus isolation

Procurement Notes

Verify the specific suffix (e.g., BRWZ-RL) against the manufacturer's current ordering guide to confirm packaging type and channel configuration. Ensure compatibility with system voltage levels and isolation requirements before procurement. Cross-reference datasheet revisions for any parameter updates.

Selection Notes

Select this component when high-speed digital isolation is required with low power consumption compared to optocouplers. Consider the 16-SOIC package constraints and thermal performance. Verify that the 10 Mbps data rate meets application timing needs and that the 3750 Vrms isolation rating satisfies safety standards.

Part Context

This part belongs to the ADuM141x series of quad-channel digital isolators. It shares the iCoupler architecture with other models in the family but differs in data rate and channel configuration. It serves as a direct replacement for legacy optocoupler solutions in space-constrained designs requiring robust signal integrity.

Replacement Considerations

Check for ADUM1412ARWZ-RL for similar specifications with potential minor parameter variations. Verify pinout compatibility with existing PCB layouts when substituting. Confirm that alternative packages meet mechanical and thermal requirements.
