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

2.1 TPA3116D2 AIYIMA 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. The system is powered by DC voltage in the range of 12-24VDC (you can choose a connector or traditional 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 3.5-8 Ohm.
