Digital Isolators are used in a variety of applications, including industrial, medical, automotive, aerospace, consumer, and military systems. The ADUM3470ARSZ-RL7 is a single, 8-bit digital isolator designed to provide superior performances in power supply, isolation and EMI/RFI noise rejection. The ADUM3470ARSZ-RL7 is comprised of a high-speed microprocessor based RISC microcontroller and a set of 8 opto-isolators, each driven by an Infineon BGT28N60 MOSFET.

The ADUM3470ARSZ-RL7 works by isolating the driver side from the receiver side of the isolation barrier. The 8-bit driver on the driver side is driven by a low-voltage logic signal, while the opto isolators on the receiver side are driven by the dedicated RISC microcontroller and the Infineon BGT28N60 MOSFET. The ADUM3470ARSZ-RL7 provides a 0.8ns maximum rise time and 0.8ns minimum fall time for maximum data rate. This ensures that the data sent from the driver side is correctly received by the receiver side with high fidelity and accuracy.

The ADUM3470ARSZ-RL7 is used to isolate digital signals in a wide range of applications. In industrial automation, it is used to reduce the possible risk of short-circuiting and electrical noise interference that could cause equipment failure and operational problems. In medical systems, the isolator is used to safely transfer sensitive medical data from one device to another. In automotive systems, the isolator provides isolation between the driver-side electronics and the passenger-side systems. In addition, this device is used to provide high-speed signal transmission and data exchange in consumer, aerospace, and military applications.

The ADUM3470ARSZ-RL7 is also highly reliable and robust, with a wide input voltage range from 2.3V to 5.5V and a wide temperature range from -40° to +125°C. The device operates at a maximum frequency of 400kHz and provides 1.5kV RMS isolation for 1 minute. It also offers a high level of EMI/RFI rejection for improved noise immunity, and allows for low start-up current of only 10µA.

Overall, the ADUM3470ARSZ-RL7 is an excellent digital isolator, which offers improved performance, reliable operation, and cost-effectiveness in a wide variety of applications.
