TPA3255 Digital Class D HIFI Audio Amplifier Board 300Wx4 High Amplifier BV9J7 The TPA3255 is a high performance Class D power amplifier with Class D efficiency and capable of delivering true high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra HD). This technology enables the device to maintain ultra-low distortion across the entire audio frequency band while delivering sound quality.The device operates in AD mode, can drive up to two 315W/4R loads and two 150W (unclipped power)/8R loads at a of 10%, and features a 2 VRMS analog input interface that supports interfacing with high-performance DACs (eg TIs PCM5242) seamlessly. In addition to excellent audio performance, the TPA3255 combines efficiency with ultra-low power stage idle losses ( 2.5W).This can be achieved with an 85mR MOSFET with an optimized gate driver scheme. Compared with traditional discrete implementations, this scheme can significantly reduce idle losses.All parts of this product are authentic, and pure in quality; using high- is not only a of safety and quality, long service life, but also a strong that the actual performance can reach the design goal.Theresistor adopts high-precision chip resistors, which ensures a good signal-to-noise ratio of the whole machine.Adopt special magnetic ring inductance for audio to clear and powerful sound.PCB adopts 1.6mm thick double-sided board, 2.0oz copper thickness, and full tin spraying process to good passing performance of and small currents.
