It is a dual channel Class D audio amplifier board producing 8 W per channel of output into 8 Ohm load. It employs a Tripath-style Texas Instruments TPA 3110 chip to achieve high efficiency. Its excellent self-dissipation eliminates the need for an external heatsink when playing music under average listening conditions, making it perfect for hi-fi applications. The module dissipates only 0.3W with no signal when in ON mode (around 0.006W when in stand-by). Its reliability and longevity is ensured by a variety of protection including over/under voltage protection, over current protection and over temperature protection. Integration of high-quality SMD and MKP plug-in capacitors ensures hi-fi amplification output.
