TSA8802A is a 2x100W 2 channels DSP amplifier board, it's a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3221) and 2 channels have 100W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-30V power supply. It can be used to drive any 2Ω~8Ω passive speakers.

The highlight point is ADAU1701 DSP chip on board. It has a default DSP program loaded. Customers can adjust the gain, bass, midrange and treble in the DSP program. It also have a debug port for Sigima Studio, User can program this module with our USBi programmer to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. TSA8802A is the base board of TSA8802B. You can also plug a AudioB I2S module to the board, then it becomes a Bluetooth audio amplifier.

External Buttons port:

Not support this function on TSA8802A.


Volume control POT port:

There have an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume,treble,middle,Bass. You need update the DSP program first. DSP program (with external POTs). This is our POT kit

  1. ADC0- Main volume.
  2. ADC1- Bass volume.
  3. ADC2- Middle volume.
  4. ADC3- treble volume.


DSP programming port:

User can load a new DSP program by using the USBi JTAG Sigma DSP programmer




Specifications typical @ +25℃, Powered by 24V DC, unless otherwise noted. Specifications subject to change without notice.
