Ntroduction of TPA3255 :

TPA3255 is a high-performance Class-D power amplifier chip, which has Class-D efficiency and can bring true high-end sound quality circuits. The device features advanced integrated feedback design and a proprietary high-speed gate driver error correction function (PurePath ™ Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the entire audio frequency band while exhibiting perfect sound quality. The device operates in AD mode. When THD is 10%, it can drive up to two 315W / 4R loads and two 150W (unclipped power) / 8R loads, and has a 2 VRMS analog input interface to support high-performance DAC (Eg TI's PCM5242) seamless connection. In addition to excellent audio performance, the TPA3255 also has the advantages of high power efficiency and ultra-low power level idle loss (less than 2.5W). Compared with the traditional discrete implementation scheme, this scheme can significantly reduce idle loss.
