Amplifier Board TPA3116D2 100W NE5532 OPAMP 8-25V Subwoofer  Audio Module

The product uses the new US TI company TPA3116D2 high-performance power amplifier chip as the core, DC single power supply 8-25V wide working voltage, 50W (left channel) + 50W (right channel) two-channel output, the efficiency is up to 90%. Can use switching power supply, laptop switching power supply, battery or car power supply, etc...

  • Power supply range: DC8-25V
  • Number of channels: mono(Subwoofer output)
  • Output power: 100W
  • PCB size: 75X60MM

Turn the knob to the bottom to turn off the state


Optional matching power supply:
The power connector is a standard 5.5MM power jack, the same as most notebook power supplies.
The power supply for the board is critical. The higher the voltage, the higher the current and the better the output power.
If you only have 12V 1A, it can driver  3-4 inch subwoofer . If you are above 19V 5A, there is no problem driving the 8-10 inch subspeaker, and the power supply must be highly valued.
Digital subwoofer power amplifier board with preamplifier op amp NE5532 buffer matching.
Delivery is subwoofer amplifier, if you want to full frequency version, please contact us, we will send a full-frequency version. thank you!




Note:

1. The audio input is sufficient, and the output voltage is sufficient if the power supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power.

 

2. The normal operation is to connect the external power supply and the digital power amplifier's power connection port, and then connect the 220V power cable of the external power supply to the mains socket. The wrong way is to first turn on the mains interface of the external power supply, and then input the output interface of the external power supply to the digital power amplifier. Because the digital power amplifier has a filter capacitor, the capacitor is charged and discharged, and a low-voltage small spark is generated within 0.1 seconds of the contact. Although the low pressure has no effect, it is also a bad habit.
