ADUM1410BRWZ

Overview

The ADUM1410BRWZ is a quad-channel digital isolator 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 provides an isolation voltage of 3750 Vrms with a common-mode transient immunity of 25 kV/µs. Typical propagation delay is 30 ns, with rise and fall times of 2.5 ns. It functions in unidirectional mode across four channels, consuming 2.8 mA on the primary side and 8.8 mA on the secondary side. The component is housed in a 16-pin SOIC package and operates between -40°C and +105°C.

Feature Summary

• Integrates four independent unidirectional signal paths using monolithic air core transformer technology for robust magnetic coupling.
• Provides high common-mode transient immunity to protect against noise in electrically noisy environments.
• Supports wide operating supply voltage ranges compatible with standard logic families.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing safety-certified signal isolation
• Power metering applications involving high-voltage sensing

Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the tape-and-reel packaging format and temperature grade. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the selected variant matches the required channel count and isolation voltage ratings for the target design.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required at moderate speeds. Compare against the ADUM1411 for inverted logic options or the ADUM1412 for dual-directional capabilities. Consider the ADUM1410E1 variant if higher data rates up to 150 Mb/s are necessary for the application.

Part Context

This part belongs to the ADUM141x series of quad-channel digital isolators from Analog Devices. The series leverages iCoupler technology to replace traditional optocouplers, offering superior performance in speed, power consumption, and size. The BRWZ designation indicates a specific reel quantity and industrial temperature rating within the broader product family.

Replacement Considerations

The ADUM1410ARWZ serves as a direct pin-compatible alternative with identical electrical specifications but may differ in manufacturing lot or minor packaging tolerances. Verify that any substitute maintains the same 3750 Vrms isolation rating and 10 Mb/s data rate capability.
