Using the NCP2824 filterless Class D amplifier can be designed a very simple low power audio amplifier electronic project, capable of delivering up to 2.4 W to a 4 ohms load with a 5 V supply voltage.
With the same battery voltage, it can deliver 1.2 W to an 8 ohms load with less than 1% THD+N. The non−clipping function automatically adjusts the output voltage in order to control the distortion when an excessive input is applied to the amplifier.

This adjustment is done thanks to an Automatic Gain Control circuitry (AGC) built into the chip. A simple single wire interface allows to the non Clipping function to be enabled and disabled.
A programmable power limit function is also embedded in order to protect speakers from damage caused by an excessive sound level.
