Digital Isolators are deployed in a wide range of applications. Among these, the ADUM7642ARQZ isolator offers a unique set of features and advantages that make it an ideal solution for many applications. In this article, we will look at the application field for ADUM7642ARQZ and its working principle.

Application field

The ADUM7642ARQZ isolator is primarily used for the isolation of digital signals. It provides isolation between different buses, such as I2C, SPI, UART, and CAN. Additionally, it is capable of providing galvanic isolation between two circuits. It is also commonly used in medical applications, due to its high EMC performance and reliability. Furthermore, it is also used in industrial automation and control systems.

Working Principle

The working principle of the ADUM7642ARQZ isolator is based on monolithic transformers. These transformers provide two signals with independent primary and secondary sections, allowing high isolation of signals across the two sections. The primary and secondary sections of the transformer have independent windings, meaning that the primary windings are not affected by the secondary windings. This provides a higher level of isolation compared to other communication isolators.

The isolator is based on optocoupler technology. This means that light is used to transfer signals across the isolated paths. The optocouplers used in the isolator employ Integrated Photonic Devices (IPDs), which are more reliable and consume less power than traditional optocouplers.

The ADUM7642ARQZ isolator also features an integrated address loop transmitter. This allows signals to be transmitted between the primary and secondary sections of the isolator using a single line. This is achieved by providing the isolator with a data rate of up to 250 kbps.

Conclusion

The ADUM7642ARQZ isolator is an ideal solution for many applications that require digital signal isolation. Its features make it a reliable and power efficient choice for medical, industrial automation and control applications. Furthermore, its optocoupler technology and integrated address loop transmitter provide high levels of isolation and faster data transfer rates.
