Digital Isolators are designed to provide reliable galvanic isolation between different digital circuits while still allowing them to communicate with each other. The AD260BND-3 isolator is designed to provide this type of isolation with a very low leakage current between the circuits. It is suitable for use in non-isolated systems as well as in isolated systems.

The AD260BND-3 isolator has several features that make it a great choice for digital isolation. The outputs of this device are open-drain and are cross-voltage compatible with different input voltages up to +/-25V. The device has an integrated ESD protection diode on the output side and is capable of driving 2-20 pF capacitive loads at a switching speed as fast as 5MHz. It is rated for a continuous current of 3A, making it suitable for use in high-current applications.

The principle of operation of the AD260BND-3 isolator is based on the concept of capacitive coupling. This type of isolation uses a thin epoxy-based dielectric layer to form a capacitance between the input and output circuits. This allows the signal to be passed through without the need for direct electrical connection, providing the necessary isolation between the circuits.

The AD260BND-3 isolator can be used in a wide variety of applications. It is ideal for use in DC/DC converters, power supplies, motor controllers, frequency counter circuitry, and any other application where isolation is required between different circuits. In addition, the device can be used as a logic-level transducer, converting a logic-level signal from one circuit to another for communication between the two.

In summary, the AD260BND-3 isolator is a versatile digital isolator that can be used in a variety of applications where robust galvanic isolation is required. Its features make it ideal for use in high-current applications, while its fast switching speed makes it suitable for many different types of digital circuits. Its low leakage current makes it an excellent choice for non-isolated systems, and its open-drain outputs and integrated ESD protection make it a great choice for isolation applications.
