Digital Isolators are specialized ICs (Integrated Circuits) that provides a high level of electrical insulation between two circuits. Unlike traditional opto-electronic isolators, digital isolators offer some additional benefits, such as a higher data rate, better reliability, and lower power consumption. The ADUM2402BRWZ-RL Digital Isolator is an ideal choice for applications in the medical, industrial automation, and automotive industry, due to its high performance and reliability.The ADUM2402BRWZ-RL is a dual-channel, constant current, digital isolator designed to isolate two physical circuits at a relatively low operating voltage of 3.3V. It contains a matched pair of high-voltage CMOS transistors; one for isolating the signal and the other for providing a constant current output. The isolation barrier is created by the presence of insulated gate bipolar transistors (IGBTs) inside the device. It also features a 3.3V power supply, an active LED indicator, and a push-pull output driver.The ADUM2402BRWZ-RL offers a 1000V DC isolation, allowing two electric circuits to exchange data with each other without potential interference, noise, or actuations. The wide bandwidth operation frequency of the device is up to 500 Mbps, which is suitable for various data transmission applications. Furthermore, its low power consumption and optically isolated circuit prevent power surges or malfunctions.The device supports a wide temperature range of -40°C to +105°C. It also offers a high signal-to-noise ratio, making it suitable for data transmission applications in harsh environmental conditions. The advantages of the integrated CMOS transistors in the device make it ideal for non-intrusive or inductive cell sensing and motor control applications.The working principle of the ADUM2402BRWZ-RL is quite simple. The two ICs in the device, the high-voltage transistor and the low-voltage transistor, are connected in series with each other, forming a bridge. The bridge is then connected to the input and output circuits to form a two-way connection. When the input signal is received, the low-voltage transistor will turn ON, triggering an electric current in the high-voltage transistor, and creating an isolation barrier between the two circuits. The output circuit will then receive the signal, but the outside noise and interference will be reduced significantly due to the isolation barrier created by the IGBTs.In summary, the ADUM2402BRWZ-RL Digital Isolator is an ideal choice for advanced industrial, automotive, and medical applications. It offers many advantages, such as high signal-to-noise ratio, wide temperature range, low power consumption, and a high isolation voltage of up to 1000V. Its simple working principle and high reliability makes it suitable for a variety of applications, from data transmission to motor control.
