Digital Isolators

Digital Isolators are a type of signal conditioning devices which facilitates the efficient transfer of digital signals between two circuits or systems, providing excellent electrical isolation between them. In comparison to other isolation techniques, such as opto-couplers or DC-DC converters, digital isolators provide a far superior signal edge rate and provide a much more efficient signal transfer even in environments with high levels of electromagnetic interference (EMI).

The ADM2490EBRWZ-REEL7 is a digital isolator from Texas Instruments which provides galvanic isolation between two communication systems, while handling 10 Mbps high-speed transfer of data between both of them. This device provides excellent high-speed data communication through its isolated side-channel controller and utilizes Texas Instruments’ patented direct-drive transformer without any internal circuitry. The transformer is designed to provide up to 2500Vrms of isolation, ensuring maximal safety in applications.

The device also provides a wide variety of features, such as an on-chip digital shuffling circuit, which allows for extended system durability and reliability. The configurable deadtime control allows for faster signal edge rates, allowing for quicker signal transfers with minimal losses. The shared pin timer features allows for synchronization and timing of the two controls systems, while providing a way for longer data packets to be sent without losing any data integrity due to the deadtime setting.

The overall design of the device is made to be optimized for dual power supply with a configurable fault timeout system; the wide 0.5V-1.8V operation mode range, allows for a wide range of application and flexibility.The device also includes ESD protection on all data lines, providing a reliable isolation even in industrial environments. It complies with UL, CSA, EN, and IEC standards, allowing it to be used in many different applications.

In summary, the ADM2490EBRWZ-REEL7 isolated digital signal controller is a robust, reliable solution for data transfers between two systems while providing an excellent level of electrical isolation and signal edge rate. Its expansive range of features and various levels of safety, make it a great choice for applications requiring high-speed digital data transfer in harsh electromagnetic environments.
