Digital isolators are electronic components that essentially block direct current or alternating current from flowing between two circuits. This type of component isolates the two components electrically, allowing coupling of signals. It is specifically used for transmission of signals between different points or systems. The specific digital isolator to be discussed in this paper is the SI8384PS-IUR.

The SI8384PS-IUR is a high isolation, no transformers used, single chip digital isolator. It features low power consumption, high isolation voltage, and low leakage current. The working principle behind this digital isolator is based on two high-performance electrical capacitors and two high-speed, small-signal, high-impedance input/output operational amplifiers. The principles of operation for the digital isolator are as follows:

The input signal (Iin) is first routed to the first capacitor (Cin). This capacitor provides isolation between the input signal and the output signal by changing the impedance of the circuit. The analog signal at this capacitor is then detected by the first operational amplifier (Ain), which then amplifies the incoming signal. The amplified signal from the first operational amplifier is routed to the second capacitor (Cout). This capacitor then provides further isolation between the input signal and the output signal. The signal is then detected by the second operational amplifier (Aout) and is amplified for the output signal (Iout).

The SI8384PS-IUR digital isolator has a wide range of applications. One of the major applications of this digital isolator is in medical equipment, such as medical imaging systems, patient monitoring devices, and diagnostic instruments. It can also be utilized in automotive and industrial applications, as well as in communication systems, such as mobile phones and Wi-Fi access points. Additionally, the SI8384PS-IUR digital isolator can be used for protection against noise, interference from capacitive coupling, and power supply for actual and isolated digital signals.

The SI8384PS-IUR is a highly versatile digital isolator that is well-suited for use in a variety of applications. Its low power consumption and high isolation voltage make it ideal for systems and devices that require isolation between different points or systems. Additionally, its wide range of applications make it suitable for use in a variety of different types of electronics. As a result, the SI8384PS-IUR is an ideal choice when it comes to choosing a digital isolator.
