Class D Amplifier for ATtiny15L

Class D Amplifier for ATtiny15L
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. (more…)
