TPA3116D2 power amplifier module
Stereo audio power amplifier module with a maximum output power of 2 x 50W. The heart of the amplifier is the TPA3116D2 chip operating in the modern digital class D. The amplifier operating in class D is characterized by very high energy efficiency compared to classic AB class designs. Due to low energy losses, such a structure has lower heat losses (it heats up less), and thus no large surfaces and heat sinks are required for heat dissipation. As a result, in the relatively small dimensions of the entire amplifier module, it was possible to obtain a large output power of 50W for each channel. A wide range of supply voltage from 5V to 24V allows you to use an amplifier based on TPA3113D2, choose a power supply or install it in car audio.
Application, connecting the TPA3116D2 power amplifier is very simple. First, you need to lead the audio input signal to the line input: we have a choice of a Jack 3.55 socket or a 3-pin connector. We provide the signal from the output of, for example, a sound card, MP3, CD, DVD player, cell phone, smartphone, tablet, etc. Then screw the cables from the column or loudspeaker to the R and L out connectors. At the very end, screw the power cables to the connectors where Gnd is ground and Vcc is plus power. Maintain the correct polarity connection and give the DC voltage in the range from 5 to 24V. The amplifier is then ready for operation. The potentiometer is used to regulate the gain or volume.
