AD260AND-4

Overview

The AD260AND-4 is a five-channel digital isolator from Analog Devices, utilizing IsoLogic magnetic coupling technology. It operates with a single 5 V power supply and features unidirectional signal transmission. The device provides 1750 Vrms isolation voltage and supports data rates up to 20 MHz. It is housed in a 22-pin PDIP package and functions within an operating temperature range of -25°C to +85°C.

Feature Summary

• IsoLogic magnetic coupling architecture for high-speed digital isolation
• Five independent unidirectional channels for control signal isolation
• Single 5 V power supply operation simplifies system design

Applications

• Isolating microcontroller signals from peripheral devices
• Industrial automation control systems
• Power electronics gate drive interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches required specifications. Check current availability status as this part may be subject to limited supply or end-of-life conditions. Ensure compliance with relevant RoHS directives if applicable to your region.

Selection Notes

Select this component when five isolated digital channels are required with moderate speed requirements up to 20 MHz. The unidirectional nature suits applications where data flows from controller to peripheral. Consider the PDIP package for through-hole mounting needs. Evaluate thermal performance within the specified -25°C to +85°C range for your environment.

Part Context

The AD260 series represents Analog Devices' IsoLogic technology, offering magnetic isolation without optical components. This family provides robust performance for digital communication across isolation barriers. The AD260AND-4 specifically addresses multi-channel isolation needs in compact packages, replacing older relay or transformer-based solutions in modern embedded designs.

Replacement Considerations

Check for AD260BND-0 or other AD260 variants with compatible channel counts and isolation ratings. Verify pinout compatibility before substitution. Ensure replacement parts meet the same 1750 Vrms isolation requirement and 20 MHz data rate specification.
