Introduction 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.
Features
With stereo RCA and wireless Bluetooth input, supporting iPod, Phone, MP3 players, TV, MP3, CD players, laptop, desktop computer or other devices input. Adopting QCC3034 Bluetooth chip that has strong compatibility with much Bluetooth devices to achieve lossless transmission.
Super large output power that can reach 300W +300W, easily to drive large passive speakers, matched very well with outdoor/ bookshelf/ computer/ desktop /ceiling /floor standing speakers.
With tone control, treble and bass can be adjusted independently to provide much delicate sound that suits different listening style,adding much fun and higher playability.
