TSA9840B is a 2x20W audio amplifier board with a newAudioB plusBluetooth module that supports Apt-X.
It has perfect class-D architecture (based on MAX98400A) and each channel has 20W power output. Both channels are capable of outputting nominal power simultaneously and continuously.
This board can be powered by any DC 10V-24V power supply. It can be used to drive two 8Ω passive speakers. TSA9840B can also be connected with ourTSA1000, TSA1010orTSA1020external audio volume control board. Users can adjust the audio volume by rotating the real knob.
The highlight point isApt-Xand TWS support. Therefore, users can stream audio to 2 pair amplifier boards at the same time wirelessly.
It is perfect for your Hi-Fi application, the audio source can be cable input or Bluetooth. You can pair up the amplifier with a mobile phone or a computer that has Bluetooth function.
Power up the amplifier board, use your phone or PC to search for a new Bluetooth device, the module will appear as "TSA9840B", you can simply pair it up without PIN. Yes, it connects automatically with your device. You can then play your audio.
