Welcome to the store!

1. High Performance: The TPA3255 chip is a high-performance amplifier chip, which has Class D efficiency and can provide true high-end sound quality. 2. Integrated Feedback, Error Correction: HIFI digital power amplifier boards feature advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath™ Ultra HD). 3. Low Distortion Sound: HIFI digital power amplifier boards allow the device to maintain ultra-low distortion across the entire audio frequency band, while exhibiting sound quality. 4. Load Capacity: The digital power amplifier board operates in AD mode and can drive up to two 315W 4R loads and two 150W (unclipped power) 8R loads when THD is 1.5%. 5. Input Interface, Connectivity: The digital power amplifier board has a 2 VRMS analog input interface, supporting seamless connection with high-performance DACs (such as PCM5242 from TI). 6. High Efficiency and Low Loss: The amplifier board has two advantages: high power efficiency and ultra-low idle loss (less than 2.5W). This is achieved by 85mR MOSFET and optimized gate driver scheme.
