NBitWonder built a class-D amplifier
Class-D amplifier is a highly efficient amplifier that operates its output devices as switches instead of as variable resistors. We posted a highly experimental version of this project last November, and it met with a surprising amount of positive feedback from the DIY community. Therefore, we developed it as a formal project.
Thanks Ben! Via the contact form.
Aren’t there ChipAmp type clones out there by now that are Class-D? Yes, with analog input and on-die A/D & PWM? Hmmm… maybe only for headphone levels?
Nice!
I really want to learn more about Class-D, especially for low current draw and reasonable output power with low distortion. … if only there were more time in the day!
