2 x 100W + 200W 2.1 Channels DSP Audio Amplifier Board - TSA8800A
20 or more $66.00
TSA8800A is a 2x100W + 200W 2.1 channels DSP amplifier board. TSA8800A is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3221) and 2 channels have 100W power output and another one channel has 200W 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 4Ω or 8Ω passive speakers(Subwoofer channel can drive 2Ω speaker).
The main DSP chip on this amplifier board is ADAU1701. 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 Sigima Studio, and user can program this module with our USBi programmer to get more functions that include equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. TSA8800A is the base board of TSA8800B. You can also plug a AudioB I2S module to the board, then it becomes a Bluetooth audio amplifier.
DSP I/O port:
We provide 3 I/O pins of ADAU1701 DSP chip for use: MP6, MP7 and MP0. User can develop DSP program to fulfill different requirement. For the default DSP firmware, if you connect these pins to GND, TSA8800A will output 1kHz sine wave.
External Button port:
Not support function on TSA8800A.
Potentionmeters port:
You can connect external POTs (5K~20K) to control the Main volume, treble, middle, 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:
User can load the new DSP program by using USBi JTAG Sigma DSP programmer.
Specification:
Specifications typical @ +25℃, Powered by 30V DC, unless otherwise noted. Specifications subject to change without notice.
