Digital isolators are components that help achieve electrical isolation between two or more circuits. The ADUM2250ARIZ-RL is a digital isolator designed by Analog Devices to help achieve this kind of isolation. It is typically used in the applications in which reliability and safety are important such as factory automation, medical, and industrial communication.
Basically, the ADUM2250ARIZ-RL is a small form factor Digital Isolator integrated circuit based on iCoupler technology. It provides two channels of electrical isolation, one in each direction, to protect circuits from any kind of electric shock or short circuit. The device features a galvanically isolated, bidirectional bus interface with 5/10 kV/μs minimum common-mode transient immunity. It offers low power dissipation and high EMI and ESD electromagnetic interference immunity.
The working principle of ADUM2250ARIZ-RL is fairly straightforward. The device consists of two isolated channels, one controlling and one controlled. It uses capacitive coupling (the iCoupler technology) to transfer the digital signal from one side to the other, without direct electrical connection between the two channels. The power isolation afforded by this separation prevents any current flow between channels at any given time. Therefore, if any voltage or electric shock accidently enters the controlled side, it will not affect the controlling side.
In addition, the ADUM2250ARIZ-RL also employs a safety system to ensure the device will hold up in a highly volatile environment. It comes with an integrated watchdog timer which constantly checks to make sure both sides of the device are functioning normally. If the signal on either side stops transmitting or is corrupted, the timer will reset the device and ensure that communication is re-established.
Overall, the ADUM2250ARIZ-RL is an effective, reliable, and cost-efficient digital isolator. It is suitable for a wide range of applications involving safety and reliability such as factory automation, medical, and industrial communication. With its capacitive coupling and integrated watchdog timer, it is able to ensure the safe and continuous transmission of digital signals even in an extremely volatile environment.
