The TPA3116D2 100W Digital amplifier board can be used as a standard mono power amplifier board or a subwoofer power amplifier board, with the NE5532 buffer matching of the front-stage op amp.
Specifications
Amplifier chip: TPA3116D2
PCB size: 75X60MM
Output power: 100W
Impedance: 8ohm
Channel: Mono
The power connector is a standard 5.5MM power jack, which is the same as most laptop power supplies.
Power supply range: DC8-25V
Note:
The power supply of the board is very important. The higher the voltage, the higher the current, and the greater the output power. If you only have 12V 1A, you can use a 3-4 inch speaker. If you are above 19V 5A, you can use a 8-10 inch speaker
Normal operation is to connect the external power supply and the power connector of the digital power amplifier first, and then connect the 220V power cord of the external power supply to the mains socket.
