Digital Isolators

The ADUM3211WARZ is a digital isolator for use in applications that require galvanic isolation. It is featured with an optically isolated interface that provides high-speed digital communication between two isolated systems while preventing the electromagnetic interference (EMI) and other forms of electrical noise from distorting the signal.

The ADUM3211WARZ optical isolator can be used in a variety of applications, including industrial, automotive, medical, telecom, networking, and defense applications. It is designed to provide reliable and secure signal transfer across multiple isolated devices. In addition, it is designed to protect against voltage and current surges while maintaining a stable signal across the isolated interface.

The ADUM3211WARZ isolator utilizes an optically isolated D-type gate, which is connected to an LED light source and a photodetector. The LED creates a beam of light, which is received by the photodiode which is connected to the input device. The photodetector then creates a digital signal, which is transmitted to the output device. This isolator is featured with a data rate of up to 167 Mbps, making it suitable for high-speed communication.

In order to ensure that the emitters and receivers are synchronized, the ADUM3211WARZ isolator uses an inbuilt synchronization circuit that is integrated into the device’s output interface. This allows the device’s output interface to match the timing of the input, making sure that the output is received in the correct order and at the correct speed. Additionally, the synchronization circuit is also used to ensure that the transmitted and received signals are within the same frequency range.

The ADUM3211WARZ isolator can withstand a wide range of temperatures, making it suitable for applications in a wide range of environments. Additionally, it is designed to be immune to dust, moisture, and shock. It also complies with the IEC 61000-4-2 and FCC Part 15 standards. As such, it is an ideal solution for applications that have stringent safety and EMC requirements.

The ADUM3211WARZ is designed to provide reliable signal transfer between two isolated systems while maintaining noise immunity and preventing EMI. With its optically isolated interface, it allows for high-speed digital communication across multiple isolated devices while protecting against voltage and current surges. Additionally, its inbuilt synchronization circuit ensures that the input and output signals are sent and received in the correct order at the right speed. It is thus ideal for applications that require secure signal transmission and stringent EMC and safety requirements.
