This device features advanced integrated feedback design and proprietary high speed gate driver error correction function (High Definition). This technology allows the device to maintain ultra low distortion throughout the entire audio frequency band while exhibiting perfect sound quality. This device operates in AD mode and can drive up to 2 x 315W 4R loads and 2 x 150W (unshipped power) 8R loads at a THD of 10%. It also features a 2 VRMS analog input interface that supports seamless connection with high performance DACs (such as TI PCM5242). In addition to excellent audio performance, the TPA3255 also combines two major advantages: high power efficiency and ultra low power grade idle loss (below 2.5W). This can be achieved through 85mR MOSFETs and optimized gate driver schemes. This scheme can significantly reduce idle loss compared to traditional discrete implementation schemes.
