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.
Blog Doing Math in FPGAs Tom Burke 23 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
