2020 New Hifi TPA3255 High Power Amplifier Board 300W +300W Digital Power Amplify Finished Board Bluetooth 5.0 Class D
Description
TPA3255 is a high performance class D power amplifier chip, which has class D efficiency and can bring true high-end sound quality circuit. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PUREPATH) ™ UHD). This technology enables the device to maintain ultra-low distortion over the entire audio frequency band while displaying perfect sound quality. The device works in AD mode. When thd is 10%, the device can drive up to two 315w / 4R loads and two 150W (uncut power) / 8R loads, and has a 2 VRMs analog input interface, which supports seamless connection with high-performance DAC (such as TI&x27;s pcm5242). In addition to its excellent audio performance, tpa3255 has the advantages of high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved with an 85mr MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation scheme, this scheme can significantly reduce the idle loss.
This product is designed for the most fastidious and high fever musicians. It integrates tpa3255 power module with very low distortion and qcc5125 which supports LDAC and aptx. It also integrates pcm5102a high-end decoding chip. Other materials are not cost-effective. Therefore, it has excellent listening performance, rich low-frequency, warm voice and high-frequency penetration. And with two high bass adjustment, easy to use
