2 x 100W Class D Bluetooth Audio Amplifier Board - TSA7498

This is a 2x100W audio amplifier board with AudioB plus Bluetooth module. It's integrated ST high performance TDA7498 which support dual channel audio amplification. Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC14V-39V* power supply. It have a smart cooling system, the fan not working in normal case to reduce the noise. Only start when the chip temperature > 65°C.

It's perfect for your Hi-Fi application, the audio source can be RCA input or Bluetooth. Compatible with all Bluetooth devices that support media audio, including iPhone,Android. Let your smartphone paired with this board, play a music. So easy!


 

Note: We had tested it. It also works well with 12VDC power. But we suggest use DC14V-39V power if possible.
