re: Enhancing performance and reliability in high-power Class D audio amplifier designs

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.

What about IM or Intermodulation distortion? Women report that the music is "too loud" with even "small" amounts of IM present.

Very usefull article. It would be intresting to add something about electromagnetic interference (EMI) and layout tips that dramatically affect the switching amplifier performance.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
