TPA3116D2 v2.1 2*50W+100W Audio Amplifier Module

2.1 TPA3116D2 stereo audio amplifier module (left and right channel) and subwoofer. The amplifier is based on the TPA3116D2 chip operating in digital class D, thanks to which it is characterized by low power losses and is small in size. In addition, the amplifier has 1 channel to operate the subwoofer. Low-pass filter based on the NE5532 low-noise operational amplifier (available in a through-hole or SMD housing). The system is powered by DC voltage in the range of 12-24VDC (you can choose a connector or traditional ARK terminals). The module is equipped with 3 potentiometers to control the volume, stereo and subwoofer. On the board you will find a 3.5 mm Jack audio input and an additional 3-pin audio connector. The amplifier can work with speakers with an impedance of 4-8 Ohm. To use the full power of the amplifier, the system should work with 4 Ohm speakers and be powered by 24VDC.
