Audio amplifier with digital input and power and headphone output stage
Abrman, Milan ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
The aim of this thesis is design and construction of amplifier for high quality home listening experience. Device is able to process both analogue signal and high sampling frequency digital input with high audio bit depth. Scope of the thesis covers the design of all the functional units: input signal circuit, S/PDIF receiver, D/A converter, high performance class D amplifier and precise headphone amplifier for dynamic sound presentation. Thesis also cover design of all control circuits containing rotary encoder with button input, microcontroller unit, digital potentiometer and segment display.
