The CMoy amplifier is a simple pocket-sized headphone amplifier originally designed by Chu Moy. It is built around a dual operational amplifier (op-amp) like the OPA2134 or NE5532 and can easily fit inside a mint tin. Technical Specifications Dual ±plus or minus 9V (or a single 9V battery with a virtual ground divider)

For digital access, Texas Instruments and other manufacturers provide reference design PDFs with detailed PCB layer plots, schematics, and bills of materials (e.g., PMP9774 envelope‑tracking power supply).
