ADUM1311ARWZ

Digital Isolators Overview

The ADUM1311ARWZ is a triple-channel digital isolator utilizing iCoupler technology. It provides unidirectional signal isolation with a data rate of 1 Mb/s and an insulation voltage of 3750 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing typical power supply currents of 1.8 mA and 2.2 mA per channel. It features a propagation delay of 100 ns and rise/fall times of 2.5 ns. The component supports pulse widths up to 1000 ns and functions across an operating temperature range of -40°C to +105°C.

Digital Isolators Feature Summary

• Integrates three independent digital channels for high-density signal isolation
• Employs monolithic air-core transformer technology for magnetic coupling
• Provides robust common-mode transient immunity at 25 kV/µs
• Supports standard logic levels without requiring external bias components

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal interfaces
• Power electronics gate drive circuits
• Inverter and motor drive isolation stages

Digital Isolators Procurement Notes

Verify the specific suffix (e.g., ARWZ) against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets. Check authorized distributor availability as supply constraints may affect lead times. Ensure the ordering part number matches the required channel count and isolation rating.

Digital Isolators Selection Notes

Select this component when three isolated channels are required in a single package. Verify that the 1 Mb/s data rate meets system timing requirements. Ensure the 3750 Vrms isolation rating satisfies safety standards for the application. Confirm that the SOIC-16 package dimensions fit the PCB layout constraints. Validate that the operating temperature range covers the environmental conditions.

Digital Isolators Part Context

This device belongs to the ADuM131x family of digital isolators from Analog Devices. It shares architectural similarities with other iCoupler-based products but offers specific channel counts and performance metrics. The series is designed to replace traditional optocouplers in applications requiring higher speed and reliability.

Digital Isolators Replacement Considerations

Consult official substitution guides for equivalent parts. Verify pin compatibility and electrical parameters before replacing. Ensure the substitute maintains the required isolation voltage and data rate.
