ADUM1412ARWZ

Overview

The ADUM1412ARWZ 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 supports data rates up to 1 Mb/s. The device provides an isolation voltage of 3750 Vrms and a common-mode transient immunity (CMTI) of 25 kV/µs. Key electrical parameters include a typical propagation delay of 65 ns, with rise and fall times of 2.5 ns. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent bidirectional channels using monolithic air core transformer technology for high-speed signal transmission.
• Provides robust galvanic isolation with a rated insulation voltage of 3750 Vrms and high common-mode transient immunity.
• Combines high-speed CMOS logic with magnetic coupling to eliminate the need for external isolation components.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise environments

Procurement Notes

Verify the specific suffix 'ARWZ' corresponds to the SOIC-16 package and lead-free RoHS compliance status required for your assembly process. Confirm that the unidirectional channel configuration matches your circuit design needs. Ensure compatibility with your system's voltage levels and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when four isolated digital channels are required in a compact surface-mount package. It is suitable for applications demanding high CMTI and low power consumption compared to optical isolators. Consider the 16-SOIC footprint constraints and verify that the 1 Mbps data rate meets your system's bandwidth requirements.

Part Context

This part belongs to the ADuM141x series of quad-channel digital isolators. It shares the same core iCoupler technology family as related parts like the ADUM1410, differing primarily in internal channel configurations or pinouts. The series represents Analog Devices' solution for replacing traditional optocouplers in modern interface designs.

Replacement Considerations

Direct substitutes within the same family include the ADUM1410ARWZ. Verify functional equivalence regarding channel directionality and pinout compatibility before substitution. Cross-reference datasheets to ensure identical isolation ratings and package dimensions match the existing board layout.
