Digital Isolators are important in electrical circuits which require a signal to be transferred isolation in order to prevent ground loops, eliminate interference, and provide electrical protection.ADUM4402CRIZ isolators are semiconductor-based digital isolators with very low total power dissipation and wide supply voltage range.They offer high performance and robustness in signal isolation and coupling needs.Application of ADUM4402CRIZADUM4402CRIZ can be used in a wide range of application fields where electrical isolation is required. In addition to medical systems, industrial control systems, high-density communications systems, and data transmission systems, ADUM4402CRIZ can also be used in monitoring and security systems, test and measurement equipment, automotive systems, aerospace systems, consumer products, and even many other general applications.One of the main application areas for ADUM4402CRIZ digital isolators is in remote sensing and telemetry applications.For example, they can be used to transfer signals across long distances over optical fiber cables in order to measure the temperature, pressure, or humidity of a remote environment.ADUM4402CRIZ can also be used to interface two different systems with different voltage levels and/or technologies.The isolated signal is transferred between them without fear of any noise interference, providing a reliable connection.In addition, it is also used for signal level Translation, switching, and buffering.Working Principle of ADUM4402CRIZADUM4402CRIZ digital isolators use a silicon planar transformer, as part of the core of its technology.This transformer is integrated into an isolated Module which is used to relay the signal from one side to another.The isolated module acts as a bridge between the two independent electrical circuits, ensuring that the electrical parameters on each side are properly insulated.The ADUM4402CRIZ transformer works on a digital principle, providing a transmission of digital data up to 2Mbit/s at 1000V isolation through the use of the main switching transistor.The transformer is located in the center of the isolator, while the two channels are separated by the insulation medium.The two isolated channels are connected via four capacitors and a coupling transformer.The transformer also features two input terminals and two output terminals for the transmission of digital signals between the two isolated channels.The ADUM4402CRIZ transformer uses a single-sided supply with built-in internal power draw.The digital signals transmitted through the isolator have a very low propagation delay and are protected against any kind of EMI/RFI interference due to the transformer\'s excellent noise immunity.ConclusionADUM4402CRIZ digital isolator is an essential component in a wide range of applications areas where electrical isolation is required.Its robustness, high performance, low power consumption and wide supply voltage range makes it suitable for various applications such as medical systems, industrial control systems, high-density communications systems, data transmission systems, remote sensing and telemetry applications, monitoring and security systems, and more.It provides reliable insulation and signal transmission between different systems or circuits and also offers a transmission of digital signals up to 2 Mbit/s with low propagation delay and excellent noise immunity.
