Digital Isolators provide electrical isolation between two circuits by using optical or electronic devices, blocking the flow of voltage or current while allowing data and signals to pass between the two. ADUM2251ARIZ-RL is a high performance isolation module that uses this technology. It is designed to operate with low power consumption and provides high voltage, wide temperature, and EMC-proven isolation.

ADUM2251ARIZ-RL is specifically designed for applications that require an extremely small PCB outline. It features an 8-channel digital isolator and an integrated output filter for standard protocols. It is an ideal solution for high voltage applications, where both channels need to be electrically isolated. The module can be used in a wide variety of industrial, automotive and power conversion applications.

The main application fields for the ADUM2251ARIZ-RL are for isolating high voltage circuits from the main system. It is ideal for applications that require a small outline and low costs, such as solar cell inverters, power factor correction, automotive lighting and power systems, voltage regulators, displays, and motor driver applications. These are just a few applications where the ADUM2251ARIZ-RL can be used but it can be applied to many others.

The ADUM2251ARIZ-RL’s working principle is based on a highly-efficient and advanced isolation technology called Dynamic Coupling. This technology relies on a combination of capacitors, inductors, and resistors to transfer data and signals between an input and output channel. The module uses a switchable capacitor network to modulate the input voltage so that the output voltage can be adjusted accordingly. This enables the module to provide isolation and accurate signal transmission without any external power.

This module also features an output filter, which ensures optimal performance and reduces the emissions that the device produces. The output filter further enhances the device\'s performance by helping to reduce common noise that is typical of digital isolators.

In conclusion, the ADUM2251ARIZ-RL digital isolator is a highly efficient, low power, small outline solution that provides excellent isolation for a variety of applications. It is ideal for high voltage circuits due to its ability to accurately transfer data and signals. The integrated output filter ensures improved performance in sensitive applications, while the switchable capacitor network ensures that the input and output voltages can be adjusted according to the application\'s requirements.
