ADUM6212CRSZ

Overview

The ADUM6212CRSZ is a dual-channel digital isolator from Analog Devices, featuring integrated DC-to-DC converters. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an isolation voltage of 3750 Vrms with magnetic coupling technology. Key electrical parameters include a propagation delay of 15 ns and a common-mode transient immunity (CMTI) of 25 kV/µs. It functions reliably across an operating temperature range of -40°C to +105°C and draws a typical operating supply current of 4.8 mA.

Feature Summary

• Integrates isolated DC-to-DC converters for simplified power delivery across isolation barriers
• Utilizes iCoupler magnetic coupling technology for high-speed signal transmission
• Provides robust common-mode transient immunity for noise-sensitive environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment with strict safety isolation requirements
• Power metering and energy management circuits

Procurement Notes

Verify the specific suffix 'CRSZ' corresponds to the SSOP-20 package and commercial temperature grade. Confirm that the integrated DC-DC converter functionality matches system power budget constraints. Ensure compatibility with the required logic levels and isolation voltage ratings for the target application environment.

Selection Notes

Select this component when dual-channel isolation with integrated power conversion is necessary. Compare against other ADUM62xx variants based on channel count and specific CMTI requirements. Consider the SSOP-20 footprint constraints during PCB layout design to ensure adequate creepage and clearance distances are maintained.

Part Context

This part belongs to the ADUM621x series of IsoPower digital isolators. It shares architectural similarities with single-channel counterparts but offers dual isolation paths. The series is designed to replace traditional optocouplers in applications demanding higher reliability and lower power consumption while maintaining regulatory compliance.

Replacement Considerations

Direct substitutes may include ADUM6211CRSZ for single-channel needs or ADUM6213CRSZ for quad-channel configurations. Verify pinout compatibility and thermal performance when transitioning between different package types within the same family.
