AD260AND-0

Overview

The AD260AND-0 is a high-speed digital isolator utilizing IsoLogic circuit architecture to isolate five unidirectional logic signals. It integrates an isolated power transformer providing up to 1.5 W at 37 V p-p for a 3.5 kV rms isolated DC-DC supply. The device operates on a single 5 V supply with a typical current of 4 mA. It supports a logic signal bandwidth of 20 MHz and offers a common-mode transient immunity of 10 kV/ms minimum. Operating temperatures range from -25°C to +85°C in a PDIP-22 package.

Feature Summary

• Integrates five isolated logic channels with an internal power transformer for simultaneous signal and power isolation
• Utilizes IsoLogic architecture to replace multiple discrete opto-isolators while maintaining waveform edge symmetry
• Provides robust common-mode transient immunity suitable for noisy industrial environments

Applications

• PLC and DCS analog input/output cards
• IGBT motor drive controls
• General data acquisition systems
• High-speed digital I/O ports

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix indicates the correct pin configuration and isolation rating. Check for obsolescence status as this model may be discontinued. Ensure compliance with RoHS directives if required by your manufacturing standards. Validate that the PDIP-22 package fits your PCB layout constraints.

Selection Notes

Select this component when designing systems requiring simultaneous isolation of five control lines and isolated power generation. It is suitable for replacing arrays of traditional optocouplers to reduce board space. Consider the 20 MHz bandwidth limit for signal speed requirements. Verify that the 3.5 kVrms isolation voltage meets safety standards for your application environment.

Part Context

The AD260 belongs to the AD260 family of high-speed logic isolators developed by Analog Devices. This series employs proprietary IsoLogic technology to combine magnetic coupling for data transmission with an integrated transformer for power delivery. The family includes variants with different input/output configurations, allowing flexibility in system design without changing the core isolation methodology.

Replacement Considerations

Direct replacements are limited due to the integrated power transformer feature. Review AD261 series devices for similar functionality but verify channel counts and power output capabilities match system requirements.
