TPA3255 Digital Class D HIFI Audio Power Amplifier Board

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 flawless 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 THD of 10%, and features a 2 VRMS analog input interface that supports interfacing with high-performance DACs (eg TI's PCM5242) seamlessly. In addition to excellent audio performance, the TPA3255 combines high power efficiency with ultra-low power stage idle losses (below 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, unpretentious and pure in quality; using high-quality parts is not only a guarantee of safety and quality, long service life, but also a strong guarantee 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 ensure clear and powerful sound.
PCB adopts 1.6mm thick double-sided board, 2.0oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Top-notch PCB quality.
