Digital isolators are electronic components used to separate two circuits electrically and safely, while allowing signals to pass between them with minimal distortion and latency. ADUM1400ARWZ-RL, made by Analog Devices, is one type of digital isolator. It is a bi-directional isolator, meaning it can pass signals in both directions between two circuits. The chip can be used to transform signal levels and frequencies, to provide a barrier of electrical safety between two circuits, or to convert different types of communication signals.

The ADUM1400ARWZ-RL can provide up to 6kV isolation, with a breakdown voltage of up to 300V. The device is constructed of two basic components: a high-speed dual-channel optocoupler connected to a dual-channel isolator. The dual-channel optocoupler consists of one-way signals, using two independent NPN photovoltaic cells to transfer control signals, switch settings and digital data across electrical boundaries. The dual-channel isolator is made up of two independent channels that allow data to be sent and received on both the input and output lines.

The ADUM1400ARWZ-RL operates on a single 5V supply, with a current of 150mA (typical). It has a propagation delay of 13.5ns, and a maximum data rate of 400Mbps. The device also has an operating temperature range of -30 to 70 degrees celsius, with an operating voltage range of 2.5 – 5.5V.

The ADUM1400ARWZ-RL is suitable for a wide range of applications, in particular for electrical isolation of digital signals. The device can be used to provide galvanic isolation between two different circuits, or to ensure signal strength and data integrity in high-speed digital applications. It can also be used to protect sensitive devices or subsystems from over-voltage transients, and to provide a secure connection between two devices that are not electrically connected.

The application field and working principle of the ADUM1400ARWZ-RL is as follows: the device is a bi-directional isolator that uses two independent channels for data transmission. The chip is designed to provide electrical isolation between two circuits, with a maximum breakdown voltage of up to 6kV, and a propagation delay of 13.5ns. The device operates on a single 5V supply, with a current of 150mA (typical). It is suitable for a wide range of applications, in particular for electrical isolation of digital signals.
