Digital isolators are an invaluable component in a variety of industrial, medical, and automotive electronics. ADM2487EBRWZ is a high-performance digital isolator designed to provide reliable isolation between two different systems. It provides up to 2 kV of galvanic isolation and is very reliable in its operation, even in harsh environmental conditions.

Application Field

ADM2487EBRWZ is suitable for industrial, medical, and automotive applications. In industrial applications, it is used to provide isolation between two different networks such as in PLC systems. It is also used in medical applications such as medical imaging systems, which require high-level isolation between the imaging system and other systems. In automotive applications, it is used to provide isolation between entertainment systems, navigation systems, and other related systems.

Working Principle

ADM2487EBRWZ uses an isolation process that does not rely upon capacitive coupling or inductive coupling. Instead, it utilizes a process known as transformer isolation. This process involves an optical coupler which is electrically isolated from the two systems. The optical coupler is composed of two different components, an input device and an output device. The input device converts an electrical signal into light which is then transmitted through an optical medium such as a fiber optic cable. The output device converts the light back into an electrical signal which is transmitted to the other system. This process provides high-efficiency isolation with minimal power consumption.

ADM2487EBRWZ provides complete, high-speed isolation between two different systems. It provides up to 2000 VDC of galvanic isolation and can operate from -40°C to +105°C. It features a 0.5 μs propagation time which makes it suitable for high-speed data transmission. The device has a high common mode transient immunity of 60 kV/ μs that meets the requirements of medical and industrial applications. Other features include a wide input voltage range of 4V to 18V, an internal noise filter, and overcurrent protection.

ADM2487EBRWZ is the perfect solution for industrial, medical, and automotive applications. It provides reliable and efficient isolation and is capable of withstanding harsh environmental conditions. It is the perfect choice for both high-speed data transmission and galvanic isolation.
