Digital isolators are circuits that allow for electrical isolation between components, providing electrical safety and protecting devices from noise. These isolators prevent electrical current from passing between two circuits, allowing them to process data separately without risk of interference. ADUM4153BRIZ is an example of a digital isolator and is commonly used in applications such as automotive, medical, industrial, and consumer electronics. This article will explain the field applications and working principle of the ADUM4153BRIZ digital isolator.

The ADUM4153BRIZ is designed to provide reliable noise immunity and galvanic isolation between two circuits, allowing for the safe and reliable transfer of digital data. It can be used to transmit data between devices such as computers, tablets, and smart phones, as well as other communication systems. The digital isolator also provides transient protection from power line anomalies, as well as optical isolation to reduce power supply noise.

The ADUM4153BRIZ digital isolator is useful in a wide range of applications. In automotive systems, this isolator can be used to protect vehicle systems from radio frequency interference (RFI). It can also be used in medical, industrial, and consumer electronics applications, providing protection from power surges and transient electrical noise. The isolator can also be used in telecommunications systems, as it provides reliable digital communication.

The working principle of the ADUM4153BRIZ digital isolator is based on the principle of capacitive coupling. A pulse signal is generated by using the primary side circuitry of the isolator. This pulse is then transmitted through an isolation barrier to the secondary side circuitry, where it is received and transformed into a data signal. The isolator provides high common mode rejection of up to 40dB, which ensures a high signal-to-noise ratio and reliable data transmission.

In summary, the ADUM4153BRIZ digital isolator is a reliable and versatile circuit designed to provide galvanic isolation and transient protection from power line anomalies. This isolator is useful in a wide range of applications, such as automotive, medical, industrial, and consumer electronics, as it provides reliable digital data transmission. The working principle of the isolator is based on the principle of capacitive coupling, allowing for a high signal-to-noise ratio and reliable data transmission.
