ADUM1201CRZ

Overview

The ADuM1201CRZ is a dual-channel digital isolator utilizing Analog Devices’ iCoupler technology, which combines high-speed CMOS and monolithic transformer technology. It features 1/1 channel directionality and operates with supply voltages from 2.7 V to 5.5 V. The device supports data rates up to 25 Mbps (NRZ) with precise timing characteristics, including a maximum pulse-width distortion of 3 ns and channel-to-channel matching of 3 ns. It offers high common-mode transient immunity exceeding 25 kV/µs and is available in a narrow-body SOIC-8 package.

Procurement Notes

Verify the specific suffix 'CRZ' corresponds to the standard commercial temperature range and tape-and-reel or tube packaging as defined in the official datasheet. Confirm that the component meets the required safety certifications, such as UL 1577 recognition for 2500 Vrms isolation voltage, before finalizing procurement orders to ensure compliance with system safety standards.

Selection Notes

Select this component when bidirectional data transmission is required across an isolation barrier with moderate speed requirements up to 25 Mbps. It is suitable for applications needing 3 V/5 V level translation and robust performance in noisy environments due to its high CMTI. Ensure the design accommodates the power consumption profiles at the target data rate and operating voltage.

Part Context
