Power amplifier class d is now quite crowded among the lovers of audio amplifiers because this power amplifier has a large enough power output and has a fairly slim design. Therefore, it does not provide such a large place for the size of a high power amplifier. And no less important, the amplifier has a heat that is not large compared to class AB or OCL power amplifier. And this time I will share the class-D power amplifier circuit using a chip (IC) as the main power amplifier of this D-class. Namely using TDA8950TH IC, this IC the design is very small with 16mmx14mm dimension. And for output power that can be issued this IC can reach up to 340W x 1 @ 8 Ohm; 150W x 2 @ 4 Ohm. The voltage input is wide range about 12V up to 45V DC. Below is the schematic circuit of TDA8950TH.
