The Tinysine 2x 100W 2 Channels DSP Audio Amplifier Board - TSA8802A is a versatile audio solution that integrates a DSP, DAC, and amplifier into a single board. It features a robust class-D architecture, based on the TPA3221, capable of delivering 100W power output per channel. This board is designed to drive passive speakers with impedances ranging from 2Ω to 8Ω and can be powered by any DC power supply within the 12V to 30V range.
A notable feature of this amplifier board is the inclusion of the ADAU1701 DSP chip, which comes pre-loaded with a default DSP program. Users have the flexibility to adjust audio parameters such as gain, bass, midrange, and treble through this program. Additionally, the board is equipped with a debug port compatible with Sigma Studio, allowing further customization and programming via a USBi programmer. This enables advanced audio processing functions like equalization, crossover, bass enhancement, multiband dynamics processing, and delay compensation.
The TSA8802A serves as the foundational board for the TSA8802B model and can be upgraded with an AudioB I2S module to transform it into a Bluetooth audio amplifier. It incorporates a smart cooling system and is safeguarded by over/under voltage, overcurrent, and overtemperature protection mechanisms.
