2 x 100W 2 Channels DSP Audio Amplifier Board – TSA8802A
TSA8802A is a 2x100W two-channel DSP amplifier board, a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture (Based on TPA3221), and two channels have 100W power output. All the channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-30V power supply can power this board. It can be used to drive any 2Ω~8Ω passive speakers.
The highlight point is the 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 has a debug port for Sigma Studio; the User can program this module with our USBi programmer to get more functions, which include equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. TSA8802A is the baseboard of TSA8802B. You can also plug an AudioB I2S module into the board; then it becomes a Bluetooth audio amplifier.
External Buttons port: This function does not support TSA8802A.
Volume control POT port:
There is an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume, treble, middle, and Bass. You need to update the DSP program first. DSP program (with external POTs). This is our POT kit.
- ADC0- Main volume.
- ADC1- Bass volume.
- ADC2- Middle volume.
- ADC3- treble volume.
DSP programming port:
Users can load a new DSP program using the USBi JTAG Sigma DSP programmer.
Specifications:
Specifications typical @ +25℃, Powered by 24V DC, unless otherwise noted. Specifications are subject to change without notice.
