From the project
30-Days-PCB-Design-Challenge
Day 30 / 30 — 30-Day PCB Design Challenge (Final Build)
A compact stereo audio amplifier built around the PAM8403, a filterless Class-D amplifier IC delivering 3W per channel into 4Ω at 5V supply, with attention to the output filtering, ground topology, and supply decoupling that determine whether a Class-D amp sounds clean or produces audible switching artifacts and EMI.
