Description:
TPA3255 is a high-performance class D power amplifier, it has class D efficiency and can bring true high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (For PurePath Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device works in AD mode. When the THD is 10%, it can drive up to 2pcs 315W/4R load and 2pcs 150W (unclipped power)/8R load. It also has a 2 VRMS analog input interface that supports high-performance DAC (such asPCM5242) seamless connection. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation, this solution can significantly reduce idle loss.

Features:
- Use original TPA3255*2pcs.
- Main filter electrolytic capacitor adopts a total capacity of 470UF*8pcs.
- High-precision chip resistors ensure a good signal-to-noise ratio of the whole machine.
- PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, full tin spraying process, guaranteed size. Good current passing performance. First-class PCB.
- Its output adopts red-grey ring high-current audio special inductor to ensure the sound is clear and powerful.
- When using PBTL bridge, it can output 600W+600W maximum power under 4-ohm load.
