Digital Isolators are used to protect connected devices from each other by using various forms of isolation technology such as optical, magnetic, and electrical isolators. They are also used to transmit signals among these devices. The ADUM1100AR-RL7 is a digital isolator, developed by Analog Devices, that uses capacitive-coupled isolation technology. This technology makes the ADUM1100AR-RL7 suitable for industrial control, motor control, power management, communication, and automotive applications.

The ADUM1100AR-RL7 is a 4-channel digital isolation device that can be used to interconnect two independent systems with data up to 20Mbps. It features an isolation rating of 4.5kV rms, as well as ESD immunity of 6kV contact and contactless. Its wide temperature range is from – 40˚C to + 125˚C, and operating voltage is 5.0V DC from -40°C to +105°C. The device also features low propagation delay and jitter, as well as common-mode and differential-mode transient protection for both output and input channels.

The ADUM1100AR-RL7 works by creating an electrical barrier between two independent systems with the aid of capacitive coupling. This coupling occurs between two mediums—a primary side capacitive element and a secondary side capacitive element—which are joined in a network through a differential transformer. The primary side capacitive element is connected to the signal source, and the secondary side capacitive element is connected to the signal receiver; both are contained within the digital isolator. An electrical signal is then sent from the primary side capacitive element, passes through the transformer, and reaches the secondary side capacitive element, where it is then sent to the signal receiver. This process works in both directions, allowing signals to flow in both directions.

The ADUM1100AR-RL7 offers unparalleled flexibility with its multi-functional I/O pins with three logic states. These logic states are Logic 0 (L0), tri-state (tri), and logic 1 (L1). The L0 and L1 logic levels are both digital inputs, while the tri-state is a digital output. The tri-state can be used to switch between the L0 and L1 levels, allowing the ADUM1100AR-RL7 to be used as both an analog-to-digital and digital-to-analog converter.

The ADUM1100AR-RL7 is a highly reliable digital isolation solution that is suitable for both domestic and industrial applications. Its highly efficient capacitive coupling technology provides exceptional electrical and thermal isolation between system components, while its common-mode and differential-mode transient protections protect the system from any voltage fluctuations or surges. Its multi-functional I/O pins offer unparalleled flexibility, allowing it to be used for a variety of applications, including motor control, power management, communication, and automotive.
