TPA3116D2 50W+50W Speaker Audio Amplifier with Filter HIFI Level 2.0 Stereo bluetooth Digital Power Amplifier Board
Shipping:Standard Shipping about 10-25 business days
1. TPA3116D2 is a class D power amplifier IC launched by TI, with very high index parameters. The modulation frequency can reach up to 1.2MHZ, and the high-power output distortion is less than 0.1%.
2. With AUX and Bluetooth two audio source input methods, two in one;
3. The potentiometer adjusts the volume, with a switch, it is convenient to control the volume, very suitable for DIY speakers.
4. With filter inductor, the sound is round and clear.
5. It adopts copper DC connector and fence type terminal, which can withstand high current, no heat, no damage to the wire, good wiring, and no short circuit.
6. The DC head wire is compatible with the input power interface of this product. Even if you don’t have a DC head adapter or battery, you can easily wire it.
7. The 5.0 Bluetooth version has higher transmission efficiency and longer transmission distance.
8. The power amplifier module does not contain a power supply and requires an external power supply, or it can be connected to a laptop power supply.
The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug the DC plug on the machine if it is not used for a long time.
Tip:Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the horn’s ohms, the smaller the relative sound power, please pay attention!
