The TPA3116 2 * 100W 12V-24V amplifier module is based on the TPA3116 chip. The system works in the digital class D. Amplifiers of this type are characterized by very high energy efficiency, and therefore low losses, eg given up in the form of heat. This allows you to achieve high power with relatively small dimensions.
