Digital isolators are devices which are used to electrically isolate components and circuits from one another to increase the system safety and performance. The ADUM1201WURZ55-RL7 is a digital isolator which is widely used in a variety of applications. This article will discuss the application field and working principle of the ADUM1201WURZ55-RL7.

The ADUM1201WURZ55-RL7 is a digital isolator which offers high performance and excellent isolation between logic levels in applications with demanding requirements for signal bandwidths and data rates. It is suitable for applications involving non-isolated communication protocols such as RS-485, RS-422, CAN bus and many others. This isolator can operate reliably at temperatures ranging from -40°C to +85°C, making it an ideal choice for a variety of industrial and automotive applications.

The ADUM1201WURZ55-RL7 consists of two CMOS compatible isolation ports, two ESD protection diodes and two CMOS SEL receiver matched pairs. The ports are separated by an isolation barrier which provides high levels of electrical isolation and protection. The ports are designed to provide bidirectional data transmission, allowing for two-way communication and increasing system performance and efficiency. The isolator is also designed to offer a high level of ESD protection against external electrostatic discharges.

The working principle of the ADUM1201WURZ55-RL7 is based on resistor-capacitor (RC) isolation. This type of isolation utilizes capacitors of different values to provide a capacitive link between the two ports that is of high impedance compared to the data signals. The signal travelling on the data line is converted into a sequence of pulses by the input circuits of the isolator. These pulses are then relayed across the capacitive link, before being decoded and retransmitted on the output line.

The ADUM1201WURZ55-RL7 is a reliable and high-performance digital isolator which is suitable for a variety of applications such as motor drive systems, industrial automation, medical equipment, test and measurement equipment, and many others. Its isolation barrier provides excellent protection and offers a high level of performance and data transfer rates. The working principle of the device is based on RC isolation, which makes the isolator ideal for applications with high signal bandwidths and data rates.
