915 Generation TPA3255 Level HIFI Digital Amplifier Board 300W300W HighPower 20 Channel Stereo Class D Audio Amplifier Board

2 The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function PurePath Ultra HD
3 This technology enables the device to maintain ultra-low distortion in the entire audio frequency band while displaying sound quality
4 The device operates in AD mode When the is 15% it can drive up to two 315W4R loads and two 150W unshipped power8R loads and has a unique 2 VRMS analog input interface which supports seamless connection with high-performance DAC such as the PCM5242 of TI In addition to audio performance the TPA3255 has two advantages efficiency and ultra-low idle power loss less than 25W
5 This can be achieved through 85mR MOSFET and optimized gate driver scheme Compared with the discrete implementation scheme this scheme can significantly reduce the idle loss
