ADUM1410BRWZ-RL

Overview

The ADUM1410BRWZ-RL is a quad-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS logic with monolithic air-core transformers. This component provides electrical isolation for four independent signal channels in a single package. It operates within a supply voltage range of 2.7V to 5.5V and supports data rates up to 10Mbps. The device offers a basic isolation voltage of 3750Vrms and a common-mode transient immunity of 25kV/µs. It is housed in a 16-pin SOIC_W package and is designed for operation across an industrial temperature range.

Feature Summary

• Integrates four isolated bidirectional channels using proprietary iCoupler magnetic coupling technology
• Provides robust signal isolation with high common-mode transient immunity capabilities
• Supports unidirectional data transmission with low propagation delay characteristics
• Operates on a single power supply domain without requiring isolated auxiliary power

Applications

• Industrial automation systems requiring galvanic isolation between control and field devices
• Medical equipment needing safe separation between patient-connected circuits and system electronics
• Power management interfaces isolating gate drivers from microcontroller units
• Communication bus isolation for RS-485 or CAN networks in noisy environments

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the BRWZ designation matches the required wide-body SOIC footprint and lead pitch specifications. Ensure the datasheet revision aligns with current manufacturing standards. Check for any recent product change notices regarding pinout or electrical parameter updates before finalizing procurement plans.

Selection Notes

Select this component when four isolated channels are required within a compact surface-mount footprint. Consider the 10Mbps data rate limit against application timing requirements. Evaluate the 3750Vrms isolation rating against system safety standards. Compare the 25kV/µs CMTI specification against the noise environment of the target application to ensure reliable signal integrity.

Part Context

This part belongs to the ADUM1410 series of quad-channel digital isolators from Analog Devices. The series leverages iCoupler technology to replace traditional optocouplers in many applications. The BRWZ-RL variant specifically denotes the tape-and-reel packaging format suitable for automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

Direct replacements include other ADUM1410 variants such as ADUM1410ARWZ-RL or ADUM1410BRWZ. Verify that substitute parts maintain identical pinouts and electrical characteristics. Cross-reference with ADuM140x series components if different channel configurations are acceptable.
