Digital Isolators

Digital isolators, also known as electrical insulation systems, are electronic devices that use semiconductor-based insulation techniques to eliminate electrical potential difference between two subsystems or circuits, while also providing a level of noise immunity. Digital isolators are widely used in industrial automation and consumer electronics applications as they offer higher levels of noise rejection than traditional analog isolation techniques.One of the most popular digital isolation solutions is the ADUM6202ARIZ, which provides low power, high speed isolation between two physical domains. This device is particularly useful in high speed switching applications, such as those found in communications, industrial automation, and automotive electronics.

Application Field

The ADUM6202ARIZ is generally used in two different types of applications. The first is in non-isolation applications, where it acts as an efficient, low power, digital glue or translator between two subsystems. In this type of application, the ADUM6202ARIZ provides an accurate level of digital transfer function between the two subsystems, and can be used to enable absolute isolation by clamping the two sides together.The other application field for the ADUM6202ARIZ is in devices that require high speed, high temperature differential switching. In such applications, the device is used as an active switch between the two subsystems, providing superior performance with reliable isolation. The device also provides an added level of EMI immunity from noise couplings between the two systems.

Working Principle

The ADUM6202ARIZ utilizes a unique working principle in order to provide high-performance isolation between two circuits. The device operates on the principle of charge-coupled voltage transfer, where the signals from each side of the bridge are coupled through a voltage transformer, which in turn converts the signals into a logic level. The transformation of the signals is done using capacitors and resistors, in order to minimize the power consumed by the device.Once the signals have been transformed, the ADUM6202ARIZ can then transfer the signal across two isolation grids. These two grids are impedance matched so as to maintain a consistent voltage output. The impedance of these two grids is also adjustable, allowing the user to select different levels of voltage.The ADUM6202ARIZ also uses two additional components to ensure that it operates efficiently. The first component is the S-terminal, which routes any surge currents to ground. The second component is the C-terminal, which functions as a damping resistor to prevent potential oscillation of the signal as it is transmitted across the grids.Overall, the ADUM6202ARIZ makes use of an efficient and reliable isolation technique to provide high speed differential switching between two subsystems. The device also provides a high level of EMI immunity, making it an ideal choice for applications that require data transmission between two isolated systems.
