ADUM1200CRZ

Overview

The ADUM1200CRZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 2/0 channel directionality with unidirectional signal transmission. Key electrical parameters include a data rate of 25 Mbps, isolation voltage of 2500 Vrms, and common-mode transient immunity of 25 kV/µs. The device operates on a supply voltage range of 2.7 V to 5.5 V, with a maximum propagation delay of 45 ns. It is housed in an 8-SOIC package and supports an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic transformer technology for robust signal isolation.
• Provides bidirectional power isolation capability without requiring isolated onboard power supplies.
• Offers superior performance over optical couplers with higher data rates and lower power consumption.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage isolation requirements

Procurement Notes

Verify the specific suffix (CRZ) to confirm the commercial temperature grade (-40°C to +105°C) and SOIC-8 package variant. Ensure compatibility with your PCB footprint and reflow soldering profile. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel, unidirectional isolator is required for general-purpose digital signals. It is suitable for designs needing 2500 Vrms isolation with moderate data rates up to 25 Mbps. Consider the 8-SOIC package constraints and thermal management capabilities within the specified industrial temperature range during circuit layout.

Part Context

This part belongs to the ADuM1200 series of iCoupler digital isolators. It represents a family of devices that replace traditional optocouplers by integrating transformers directly onto the silicon die. This approach reduces size, improves reliability, and offers better performance consistency compared to discrete optical components.

FAQ

What is the channel directionality of the ADUM1200CRZ?

The ADUM1200CRZ has a 2/0 channel directionality, meaning it provides two unidirectional channels from input side 1 to output side 2.

Does the ADUM1200CRZ require an isolated power supply?

No, the device does not require isolated onboard power supplies; it can operate with separate ground references on each side while maintaining isolation.
