The ADUM121N0WBRZ is a member of the digital isolators family. It was designed to help isolate analog circuits and provide them with an isolation barrier. This device provides galvanic isolation of up to 5kV and offers high performance isolation with a wide range of operating temperatures.

ADUM121N0WBRZ isolator uses a duplex digital isolation technique that provides galvanic isolation while simultaneously providing data transmission. It consists of two identical and symmetrical isolator channels with each channel having two channels, one for the transmission side and one for the receiver side. The device works in full, half and quarter-duplex modes. The half-duplex mode allows for simplex communication, while quarter-duplex mode allows for two-way digital communication. The full-duplex mode allows for simultaneous transmission and reception.

The device utilizes Analog Devices’ proprietary iCoupler digital isolation technology, which is based on magnetic induction to provide a reliable isolation barrier between electronics circuits. The iCoupler technology eliminates the need for discrete electrical isolation components, such as optocouplers, and allows for higher data transfer speeds. The iCoupler technology is suited for a wide variety of applications, including fully Isolated communication, industrial automation, and building control systems.

The device is capable of providing high isolation of up to 5kV rms, making it ideal for applications that require reliable performance in harsh environments. It also supports data rates up to 10 Mbps. It also features a low power operation of 5 mW, making it suitable for low power applications.

The application of the ADUM121N0WBRZ digital isolator is mainly for binary logic signals, analogue inputs, and other signal formats. It has applications in isolated industrial automation, as well as in medical, automotive, and aerospace applications. In the industrial automation field, it is commonly used for safety communication, power system control, and data transmission. The device is suitable for system designers who need high performance isolation to protect sensitive analogue equipment in high-voltage environments.

The ADUM121N0WBRZ digital isolator works by using its two channels to simultaneously transmit and receive electrical signals. It does this by converting the electrical waveform of the signal into a digital signal, which is then transmitted through the isolation gap. On the receiving end, the digital signal is converted back into its original electrical waveform, allowing the signal to be passed through the isolation barrier with minimal signal loss and distortion. This eliminates the need for optocoupler-type devices and provides a reliable source of isolation.

In summary, the ADUM121N0WBRZ is a digital isolator that provides galvanic isolation of up to 5kV and is suitable for a wide variety of industrial automation, medical, automotive, and aerospace applications. The device utilizes Analog Devices’ proprietary iCoupler digital isolation technology to provide reliable isolation of sensitive analogue equipment in high-voltage environments. It also supports data rates up to 10 Mbps while operating at a low power of 5mW.
