Digital isolators are electrical devices designed to transfer signals between two circuits while keeping the two circuits electrically isolated from each other. ADUM5403ARWZ is a digital isolator designed based on iCoupler technology. This device is fully integrated into one package and features full magnetic and optoisolation for enhanced isolation voltage and reliability, extended temperature range and high performance.

The application field of ADUM5403ARWZ covers both industrial and consumer electronic sectors. Its ability to operate under extended temperature range and provide reliable electrical isolation makes it suitable in applications ranging from typical HMI, motor control, servo, robot control, encoders, industrial motion control, logic level drive, and digital audio systems, to consumer electronic products such as automated home appliances and consumer audio-video products. This digital isolator also ensures high voltage and power integrity in medical workstations, medical diagnostic equipment, surgical tools, and critical medical imaging applications, as well as in robotic and prosthetic devices for medical applications.

Working with the iCoupler technology, ADUM5403ARWZ can be used to bridge analog and digital control signals between two points while maintaining galvanic isolation voltage between the two points. The device operates using magnetic field coupled signals to create a single-channel digital isolator. The dual iCoupler core structure uses a pair of transformers embedded inside the EP7. This core structure provides a reliable isolation barrier that is capable of withstanding isolation voltage up to 5.6kV for up to 1750V dV/dt. In addition, the low input capacitance of the digital isolator makes it ideal for driving high-speed Controllers and Gates.

ADUM5403ARWZ also includes several advanced features. These features protect the components from overvoltage, overcurrent, and clock jitter. The device supports LVTTL communication with input and output signal levels of up to 3.3V TTL. Other features include a high EMC tolerance generated by the magnetic isolation technology, a low power consumption, and a temperature range of -40°C to +105°C.

In conclusion, the ADUM5403ARWZ is a digital isolator suitable in various application fields, ranging from industrial to consumer and medical sectors. It operates based on iCoupler technology and provides electrical isolation up to 5.6kV, while also featuring high-speed communication, EMC tolerance, and a wide operating temperature range.
