ADUM3200CRZ

Overview

The ADUM3200CRZ is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides an insulation voltage of 2500 Vrms and exhibits a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a propagation delay of 45 ns, with rise and fall times typically at 2.5 ns. It functions in unidirectional mode with two channels, drawing operating currents of 3.8 mA and 7.7 mA on the respective sides. The component is rated for operation between -40°C and +105°C and is housed in an SOIC-8 package.

Feature Summary

• Employs proprietary magnetic coupling technology to provide robust galvanic isolation without optical components.
• Features enhanced system-level ESD reliability to withstand high electrostatic discharge events.
• Offers high common-mode transient immunity of 25 kV/µs for noise-resistant performance in electrically noisy environments.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix (e.g., CRZ vs. CRZ-RL7) against your bill of materials, as packaging formats differ between tubes and reels. Confirm current availability status directly with authorized distributors, as supply constraints may apply. Ensure RoHS compliance documentation matches the manufacturing date code required for your assembly process.

Selection Notes

Select this component when bidirectional data transfer is not required, as it supports only unidirectional channels. Compare power consumption requirements against the specified 3.8 mA and 7.7 mA operating currents. Ensure the 2500 Vrms isolation rating meets the safety standards of your target application environment.

Part Context

This part belongs to the ADUM3200 series of general-purpose digital isolators. It shares the same core isolation architecture and pinout compatibility with other variants in the family, differing primarily in packaging options and temperature ranges. It serves as a direct replacement for legacy optocouplers in designs demanding higher speed and lower power consumption.

Replacement Considerations

The ADUM3200CRZ-RL7 is the reel-packaged equivalent of this tube-packed component. Verify pin-to-pin compatibility if substituting with other dual-channel isolators from different manufacturers, ensuring isolation voltage and CMTI ratings are equal or superior.
