Digital isolators are devices that provide noise immunity while achieving a high level of isolation. The ADUM3480ARSZ-RL7 digital isolator is designed to allow noise-free communication between systems operating at different voltages and in high-speed applications. It is a high-speed digital isolator, enabling data to be securely transmitted between two isolated systems without noise and signal degradation.

The ADUM3480ARSZ-RL7 features a compact, low-profile package with a wide industrial temperature range of -40°C to +105°C,-40°C to +125°C. It is also flexible in terms of bus speed, allowing data rates from 4 Mbps up to 200 Mbps and providing the scalability required for automated logistics, industrial automation, automotive and medical applications.

The ADUM3480ARSZ-RL7 operates in two distinct modes for different applications. In the low speed mode, the digital isolator is optimized for signal opto-coupling, providing a bandwidth of up to 4 Mbps. In the high-speed mode, the isolator is optimized for signal transmission over optical channels and provides a bandwidth of up to 200 Mbps for data rates. The operating modes can be selected via the on-chip register.

The ADUM3480ARSZ-RL7 utilizes an advanced hybrid opto-coupler technology to achieve high performance Isolation. It operates by converting electrical signals into optical signals, then back to electrical signals on the other side. This process is done through the use of an optical transmitter and an optical receiver. The opto-coupler is controlled by two integrated photodetectors and LEDs.

The ADUM3480ARSZ-RL7 also includes an advanced analog front-end design, which allows it to have a propagation delay of 3.5ns. This is significantly lower than comparable parts, providing a high-speed performance without sacrificing noise immunity. The ADUM3480ARSZ-RL7 has a propagation delay of 160ns, making it an ideal choice for applications requiring high performance and speed.

The ADUM3480ARSZ-RL7 also has multiple self-protection features, such as an integrated over-temperature protection and an on-chip watchdog timer. These features are designed to prevent damage from Thermal runaway and short circuit conditions to ensure reliable operation and increase the service life of the part.

The ADUM3480ARSZ-RL7 is designed to provide a low power solution for high-speed data transmission over long distances and through noisy environments. With its advanced optical design and low power consumption, the ADUM3480ARSZ-RL7 is the perfect choice for applications in the automotive, medical, industrial automation, and telecommunications fields which require efficient data transmission in space-constrained or noisy applications.
