Note: The realization of the basic functions of 5 watts speakers, it's enough to use 1A 12V power supply. But If you want the 100w speaker, you need 3A above, 24-28V power supply.
Features: Large capacity, chip capacitors and floor with soldering. There is no solder joint on the back of the circuit board, so there is no possibility of causing a short circuit. Chip capacitors selected components and production process costs are higher than the plug capacitor. TPA3116D2 efficient Class D operation, both greater than 90% power efficiency. Low idle loss characteristics, advanced modulation system configuration, multiple switching frequency, AM interference block. TPA3116D2 for short circuit, overvoltage, overheating, undervoltage, DC and other failures to provide a comprehensive protection. In the event of an overload, the device warns the processor of the fault condition, thereby preventing itself from being damaged.
Package Included: 1 X DC 12V 24V 100W TPA3116DA Mono Channel digital Power Audio Amplifier Board
