I fully agree with the above statements concerning the benefits of digital couplers over optocouplers. However, Guy missed to mention the existance and additional benefts of other digital isolator technologies, like the capacitive coupling technology of Texas Instruments, based on silicon-oxide as isolation-material and as such an anorganic isolator, further enhancing lifetime reliablity.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
