The product integrates the extremely low distortion TPA3255 power module and the QCC5125 Bluetooth decoding module supporting LDAC and APTX. And integrated PCM5102A high-end decoding chip. Excellent high frequency penetration. And equipped with 2 high and bass adjustment for easy use.
The price of this product is relatively high, because the Bluetooth is the top matching QCC5125, also with independent decoding, and the output inductor is also expensive black crystal common mode inductor
Product Description
TPA3255 is a high performance Class D power amplifier chip. It has class D efficiency and can deliver true high end sound quality circuits. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra HD). The technology enables devices to maintain ultra-low distortion throughout the audio band while presenting perfect sound quality. The device operates in AD mode, drives up to two 315W/4R loads and two 150W (unclipped power) /8R loads at 10% THD, and has a 2 VRMS analog input interface. Supports seamless connection with high-performance Dacs such as TI&x27;s PCM5242. In addition to excellent audio performance, the TPA3255 has the advantages of high power efficiency and ultra-low power level idle loss (below 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 idle loss.
