This Class D stereo amplifier module is based on an Infineon MA5332 amplifier chip. It can deliver 2x125W at 4 Ohm, or 2x65W at 8 Ohm. A heatsink is fitted to the MA5332 chip for efficient heat dissipation. For signal input, the module accepts an single-ended stereo RCA input, via two 2-pin PCB connectors. The module's power supply accepts a range from 200 to 240V AC. Furthermore, this Class D amplifier module can be used to power other modules, such as a DAC, thanks to several power supply outputs: respectively a -/+ 12V 300MA output, a +38V 200MA output, and a +5V 1A output.
