Class D amps are simple – just take an input ... but [George] found a home for it in the power section of an amplifier. The ATtiny is clocked at 16 MHz, making the ADC clock run at 1 MHz.

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for ...
