Digital isolators are integrated circuits that help to protect critical digital subsystems in embedded systems by allowing input and output data lines to be isolated from each other while also providing necessary signal conditioning. ADUM141E1BRWZ-RL is a digital isolator from Analog Devices that is designed for high voltage applications and can work in temperatures up to 150° C. This device provides the highest level of isolation for AC assets such as signals, data, or power while also providing low jitter/distortion and high common-mode noise rejection.

The ADUM141E1BRWZ-RL isolator offers several features that make it useful for a variety of applications including automotive, telecommunications, and industrial. The device provides a high level of isolation that is not affected by frequency or temperature. It offers excellent common-mode noise rejection from 1 Hz to 100 kHz and has low capacitive coupling. The device also provides a 0.5 ms error fail-safe operation which makes it suitable for high speed data transmission.

The working principle of the isolator is based on the transformer principle of electromagnetic induction. A thin-film transformer is wrapped around two electrodes on the integrated circuit and a high voltage is used to create an alternating electromagnetic field which induces a voltage across the transformer. This induced voltage is then used to drive the input and output signals of the isolator. This mechanism ensures that the input and output signals are isolated from each other and the system is protected from high voltage surges.

The ADUM141E1BRWZ-RL isolator offers several advantages that make it suitable for high voltage applications such as automotive, telecommunications, and industrial. It provides a high level of isolation which is not affected by frequency or temperature, excellent common-mode noise rejection, a low capacitive coupling, and a 0.5 ms error fail-safe operation. This allows the device to provide reliable protection of system components from high voltage surges.
