Tiivistelmä
The goal of this project was to design an audio amplifier device in the guitar pedal form factor, which will be used for demonstration purposes of the “Darkglass electronics Oy” Exhibitor stand on Winter NAMM 2020 convention in Anaheim, USA. The second aim was to learn and understand research, development, and production processes, how from an idea and general prerequisites create a product, which will meet those requirements, and how various nuances affect those processes and final results.
The thesis consists of demonstrating device development sequence as well as device circuit analysis from simulations to board measurements. Simulations were made in LTspice software. Schematics, PCB design and production documents were created in Altium Designer software. Measurements were made using APx515 Audio Analyzer and oscilloscope.
As a result, the device was made on time. It met the requirements, and the project is considered as completed. The device is able to produce a maximum output power of 1 Watt, with a THD+N of 1%.
