The following paper contains an in-depth report on the design process of a portable DAC and Amplifier for high impedance headphones. The project brings portability into an audiophile’s world. This portable DAC and Class D amplifier takes USB data from a phone, converts it to analog, and amplifies the signal for high impedance headphones. First, the document contains motivations for the project: such as the necessity for such equipment, and who would use this product. Next, discussions of marketing considerations and customer needs bring together specifications. After, the report examines the project plan, overall functionality blocks, and estimated costs. Finally, the last chapter discusses a full description on each part of the product.
