Digital isolators are a type of integrated circuit used to transfer digital signals between two systems that use different logic levels while protecting the systems from common mode voltage differences and transient voltage surges. The ADUM6402ARIZ-RL is one of a family of Analog Devices digital isolators. It consists of an isolation channel between two isolated power domains, and a galvanically-isolated transceiver for bidirectional signal transfer. Transferring data across a digital isolation barrier is especially important in automotive, avionics and medical applications where noise immunity and system robustness is essential to system performance and safety.

The ADUM6402ARIZ-RL consists of a transmitter with opto-isolator integrated circuit (IC) core and receiver with phototransistor core. This combination provides both data transfer across one port and enables grounding of the signal\'s reference voltage to the receiver supply at the second port. It helps reduce the capacitive coupling of any high-frequency signal that can couple onto the signal line. This digital isolator also provides inherent overvoltage protection from a maximum of 5 KV continuous RMS voltage and transient protection from up to 25KV/μs.

The most important feature of the ADUM6402ARIZ-RL is its short propagation delay time of only 190 ns, making it well suited for time-critical applications. It is also able to transmit data with no lower than a 3.0 Mbps bit rate at a single channel, allowing it to transmit data quickly and reliably. In addition, it has extremely low power consumption and low noise rejection. The ADUM6402ARIZ-RL supports a wide operating temperature range from -40 to +125°C, making it suitable for a wide range of industrial temperature requirements.

The ADUM6402ARIZ-RL’s wide range of features make it ideally suited for applications in the automotive, avionics, process control, energy management, industrial automation, medical, printing, and test and measurement industries. It is also frequently used in devices such as servo drives, motor controllers, and digital power converters. Its high speed and improved performance can drastically reduce system costs, especially in power converters where it enables the conversion of high-speed digital signals without losses to the system.

In summary, the ADUM6402ARIZ-RL digital isolator is an ideal choice for a variety of applications that require high speed data transmission in conjunction with isolation and noise protection. Its short propagation delay of 190 ns, wide operating temperature range, high data rate of 3.0 Mbps, and robust protection features make it ideally suited for modern sensitive applications in harsh environments.
