product details:
The TPA3255 is a high performance Class D power amplifier that offers class D efficiency and delivers true high end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath ™ Ultra HD). The technology allows the device to maintain ultra-low distortion throughout the audio frequency band, while showing the perfect sound quality. The device operates in AD mode and can drive up to two 315W / 4R loads and two 150W (un-clipping) / 8R loads at 10% THD with a 2 VRMS analog input interface to support high performance DACs (Such as TI&39;s PCM5242) seamlessly connected. In addition to excellent audio performance, the TPA3255 combines two advantages of high power efficiency and low power consumption (less than 2.5W). This can be achieved with 85mR MOSFETs and an optimized gate driver solution. This scheme can significantly reduce the idle loss compared with the traditional discrete implementation scheme.Using imported CSR pure digital I2S output Bluetooth module, independent high signal to noise ratio DAC chip PCM5100, and high power ultra-high definition power chip TPA3255, the signal to noise ratio reached a new the height of
