ADUM1246ARZ

Overview

The ADUM1246ARZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology. It operates with a supply voltage range of 2.25 V to 3.6 V and supports data rates up to 2 Mbps using nonreturn to zero (NRZ) signaling. The device provides an isolation voltage rating of 3750 Vrms and offers common-mode transient immunity of 25 kV/µs. It is housed in an 8-lead SOIC package and functions bidirectionally without a dedicated shutdown pin.

Feature Summary

• Micropower operation enabled by proprietary iCoupler technology
• Bidirectional communication capability for two independent channels
• Enhanced system-level ESD reliability characteristics

Applications

• General-purpose digital isolation interfaces
• Industrial control systems requiring galvanic isolation
• Embedded systems with mixed-signal ground domains

Procurement Notes

Verify the specific suffix ARZ corresponds to the 8-lead SOIC package variant when sourcing. Confirm that the required isolation voltage and data rate specifications align with the application's electrical requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring low power consumption and bidirectional data transfer across isolated boundaries. Ensure the operating temperature range meets environmental constraints and that the package dimensions fit the available PCB real estate.

Part Context

This part belongs to the ADuM124x family of micropower, 2-channel digital isolators. It shares core technology with variants like the ADUM1240 and ADUM1245 but differs in packaging and specific electrical ratings defined by the manufacturer.

Replacement Considerations

Compatible substitutes within the same family include the ADUM1240ARZ and ADUM1245ARZ. Verify pinout compatibility and specific insulation ratings when substituting these parts.
