TINYSINE TSA7802A Amplifier Module TPA3116D2 DSP

TINYSINE TSA7802A: TPA3116D2 amplification chip

The TinySine TSA7802A is a 2x50W two-channel DSP amplifier module. It combines a DSP, a DAC and an amplifier for maximum flexibility. The amplification is based on a Class D TPA3116D2 chip, and has two output channels each delivering 50W at 4Ω. The power supply range of this module is 12V to 24V DC and can be used to drive any 4Ω or 8Ω passive driver.

TINYSINE TSA7802A: ADAU1701 DSP chip

The DSP part of the module is based on an ADAU1701 chip, with a default program already loaded. With this default program, you can adjust the gain, bass, midrange and treble of your music. Furthermore, if you wish to program the module yourself to include your own functions, all you need to do is use Tinyside's USBi Programmer, enabling you to include functions such as crossover, bass enhancement, multiband dynamic processing, delay compensation and so on. Furthermore, you can connect an I2S Bluetooth receiver module to turn the TSA7802A into a Bluetooth amplifier.

Despite the presence of external buttons port, this function is not supported on this model. However, you will still have access to the volume control port, on which you can connect a potentiometer kit (5K~20K) to control total volume, as well as bass, midrange and treble. To do this, you'll first need to update the DSP program (file available in the Download tab), then make the connections as follows:

• ADC0: Total volume
• ADC1 : Bass volume
• ADC2 : Midrange volume
• ADC3 : Treble volume
