The Low-Noise Headphone Amplifier was done as a final project for the course ENGR 301 (Microelectronics lab). The purpose of the project was to design the circuit using EAGLE software and create the gerber files for the final PCB board. The project included a few requirements:

• Maximum board size: 3"x3"

• 4 mounting holes in each corner

Components:

• Power Supply

• Fuse on secondary side (12 VAC), 1A

• LED Power-on indicator

• Terminals: 12 VAC, L/R Line-in, Headphone output

• Control: Dual-Gauged Potentiometer for stereo volume operation
