TPA3116D2 2x50W 4 Ohm with volume control

This amplifier module is based on a TPA3116D2 amplifier chip. This allows it to deliver a power of 2x25W under 8Ω. In addition, the architecture of this chip allows it to ensure a low level of noise and distortion, while limiting jitter thanks to an integrated clock system and a PLL circuit. As the module operates in Class D, it has a high efficiency of more than 90%. The module includes a potentiometer to easily adjust the volume level.
On the connector side, there is a 3.5mm jack connector and a 3-pin XH 2.54mm connector at the input. The output is made on screw terminals for speakers.
