AD260BND-4

Overview

The AD260BND-4 is a five-channel digital isolator from Analog Devices, utilizing IsoLogic magnetic coupling technology. It operates on a single 5 V supply with a typical current consumption of 4 mA per channel. The device provides 3500 Vrms isolation voltage and supports data rates up to 20 MHz. It features unidirectional signal transmission in a 22-pin PDIP package. Common-mode transient immunity is rated at 10 kV/µs. The component functions within an operating temperature range of -25°C to +85°C.

Feature Summary

• Implements IsoLogic architecture for high-speed digital signal isolation
• Provides robust galvanic isolation via magnetic coupling
• Supports unidirectional logic interface for microcontroller systems

Applications

• Isolating digital control signals between microcontrollers and peripheral devices
• General-purpose digital isolation in industrial automation systems
• Protecting sensitive circuitry in noisy electrical environments

Procurement Notes

Verify the specific suffix designation carefully, as variants like AD260BND-0 exist with identical core specifications but different packaging or qualification statuses. Confirm RoHS compliance requirements against the specific part number ordered, as some listings indicate non-compliance. Ensure the supplier source is authorized to guarantee authenticity for legacy components.

Selection Notes

Select this component when five isolated channels are required for unidirectional communication. It is suitable for applications needing moderate speed up to 20 MHz with high common-mode noise rejection. Consider the through-hole DIP package if PCB layout constraints favor manual assembly or prototyping over surface-mount technologies.

Part Context

This part belongs to the AD260 series of digital isolators. It serves as a replacement for traditional optocouplers by offering faster switching speeds and lower power consumption. The family focuses on providing reliable isolation for digital interfaces without the degradation issues associated with LED-based isolation methods.

Replacement Considerations

The AD260BND-0 is a documented variant within the same series. Verify pinout compatibility and package dimensions before substitution. Check if the specific application requires the exact insulation ratings or if minor differences in qualification standards affect system certification.
