ADUM1246ARSZ

Overview

The ADUM1246ARSZ is a micropower, dual-channel digital isolator based on Analog Devices iCoupler technology. It provides bidirectional communication with a data rate up to 2 Mbps NRZ. The device features high common-mode transient immunity of 25 kV/µs and operates with supply voltages ranging from 2.7 V to 5.5 V for both channels. It is housed in a compact 20-lead SSOP package.

Feature Summary

• Micropower operation utilizing proprietary iCoupler technology
• Bidirectional data transmission capability
• High common-mode transient immunity

Applications

• Industrial process control systems
• Medical equipment isolation
• Power management circuits

Procurement Notes

Verify the specific suffix ARSZ against the official datasheet to confirm the 20-lead SSOP package variant. Confirm RoHS compliance status and check for any recent product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when dual-channel galvanic isolation is required with low power consumption. Ensure the application supports the 2 Mbps maximum data rate and operates within the specified voltage range. Verify that the 25 kV/µs CMTI meets the noise environment requirements.

Part Context

This part belongs to the ADuM124x family of digital isolators. It shares architectural similarities with the ADUM1240, ADUM1241, and ADUM1245, differing primarily in pinout configurations and specific feature sets tailored for different isolation needs within industrial and commercial applications.

Replacement Considerations

Check for direct substitutes such as ADUM1240ARZ or ADUM1241ARZ if pin compatibility allows. Verify functional equivalence regarding channel count and isolation voltage ratings before substitution.
