After constructing many versions and improvements, I have come to a major conclusion: The technology for HiFi is there! The amp system can sound just as good as anything out there... I went into the research expecting to be able to tear the Class D apart. I was wrong, this is a " disruptive technology " ! The use of
Chips from the like of IR, make implementing it easy.
But what if I wanted to use paralleled driver stages? Could this part accomodate that? I don't think so. I want to switch multiple Class D drivers at the same frequency but offset the switching times so the power supply isn't hit with the high switching currents all at once. The PWM is internal and I think I can't do it with this part unless it allows an external override of the switching frequency.
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.
