TPA3116D2 AIYIMA amplifier module for 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 2 potentiometers (sensitivity and power adjustment). 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 subwoofers with an impedance of 2-8 Ohm. Specification: Working voltage range: 12-24VDC Audio input sensitivity: 500mV Frequency range: 20Hz-20KHz Impedance: 2-8 Ohm, Maximum output power: 100 W (subwoofer) Number of channels: 2-channel stereo Size: 55 x 83 x 29mm https://elecena.pl/product/22606227/aiyima-tpa3116d2-100w-subwoofer-audio-amplifier-module 2023-02-22 https://elecena.pl/product/22606227/aiyima-tpa3116d2-100w-subwoofer-audio-amplifier-module 2025-10-29
