Digital isolators are power electronic circuits that provide galvanic insulation between two systems using electrical or optical coupling techniques. Digital isolators provide a greater level of safety and isolation between components, help reduce the risk of fires or galvanic corrosion, and protect users and equipment from shocks, surges, and spikes. The ADUM1200WTRZ33 is an advanced 3.3V digital isolator that provides galvanic isolation for up to 1kV. It includes a power supply supervisor, a temperature range of -40 to +105°C, and a wide input voltage range of 2.5 V to 12 V.

The ADUM1200WTRZ33 is suitable for a wide variety of applications, including automotive, consumer, factory automation, and energy management. The device can be used in applications such as load switching, signal transmission and conditioning, analog signal isolation, and data conversion. In all of these applications, the device provides isolation, protection, and noise reduction.

The ADUM1200WTRZ33 is based on iCoupler technology, which is a combination of CMOS and monolithic-microwave-integrated-circuit (MMIC) technologies. It employs the use of a magnetic transformer as an isolation barrier between two sides of the circuit, which prevents any connection between the signal input and output. The device is capable of transmitting up to 2 Mbps of data and 1kV of isolation, making it suitable for a wide range of digital and analog applications.

The device consists of a magnetically coupled transformer, a primary side controller, and a secondary side optically isolated driver, as well as two analog and three digital lines. The magnetically-coupled transformer provides galvanic isolation between the two sides of the circuit, preventing the connection of the signal input and output and any other potential shock or surge. The primary side controller provides power supply monitoring, voltage surge protection, and a power supply supervisor. The secondary side optically isolated driver provides a galvanic isolation of up to 1kV.

The device operates on a simple working principle. At the input side of the circuit, an electrical signal is converted into a digital signal which is transmitted across the transformer, providing a high level of isolation and signal integrity. On the output side, the digital signal is converted into an analog signal and transmitted to the output. The device offers a wide range of input voltages and is capable of supporting up to 2 megabits/second data rates.

The ADUM1200WTRZ33 is an advanced digital isolator which provides a greater level of safety and isolation between components to reduce the risk of fires or galvanic corrosion, protect users and equipment from shocks, surges, and spikes, and support a wide range of input voltages. The device is based on iCoupler technology and provides a high level of galvanic isolation between the two sides of the circuit, making it suitable for a wide range of applications.
