Recently, the widespread use of amplifiers have high efficiency – 90% or more. The sound signal is converted into a PWM (pulse width modulated), which explains their high efficiency, since the output stage while working in a key mode. Modern designs of such amplifiers – a monolithic chip, integrate processor and powerful output stages. Experiment with them, for example, to change the PWM conversion algorithm is difficult. These units can get acquainted with one embodiment of the amplifier is Class D. Controller ATtiny15L AVR family firm Atmel is perfectly suited for this purpose, because it contains a ten-digit analog-digital converter (ADC) and a timer with a pulse-width modulator (PWM).
