Digital isolators are a type of circuit device that transfers digital signals from one circuit to another electrically isolated circuit. They provide a barrier between the two circuits by preventing direct current from flowing between them, allowing communication without any physical contact between the two systems. The ADUM2200ARWZ-RL is an example of a digital isolator, and its application field and working principle will be explained in this paper.

The ADUM2200ARWZ-RL is a high-speed, high-efficiency, low-power digital isolator with an operating frequency of up to 10 MHz. It features a typical propagation delay of 15 ns and a maximum data rate of 12.5 Mbps. The digital isolator is designed to protect against unpredictable signal conditions such as voltage transients, noise, and electromagnetic interference (EMI). It is capable of galvanically isolating two devices at up to 2,500 Vrms, offering superior isolation performance compared to other types of isolators.

The ADUM2200ARWZ-RL is suitable for use in a variety of applications, including medical equipment, industrial systems, and automotive systems. It provides galvanic isolation for communication systems, helping to reduce noise and other interference between systems. It is also designed to ensure system safety and reliability as it acts as a protective barrier between circuits. Additionally, the device is also used in consumer electronics applications such as HDTVs, personal computers, and digital cameras.

The working principle of the ADUM2200ARWZ-RL digital isolator is fairly simple. It consists of two sets of terminals: an input side and an output side. When a signal is sent to the input side of the isolator, the signal is converted to an electrical signal by an internal Gallium Arsenide (GaAs) switch. The signal then passes through a digital signal transformer which is capable of providing up to 2,500 volts of galvanic isolation. The signal is then sent to the output side of the isolator, where it is converted back into a digital signal.

The ADUM2200ARWZ-RL digital isolator is an effective way of transferring digital signals between two circuits while maintaining galvanic isolation. It is suitable for use in a variety of applications, including medical equipment, industrial systems, and automotive systems. The device’s simple working principle ensures that signals are transferred between two circuits without any direct current (DC) flowing between them, thus providing superior isolation performance.
