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 (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 2 315W/4R loads and 2 150W (unclipped power)/8R loads, and has a 2 VRMS analog input interface that supports high-performance DAC (For example, TI’s PCM5242) 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
1. Use original TPA3255
2. The main filter electrolytic capacitor adopts the imported famous brand Erkang with a capacity of 2200UF/63V*4 to ensure strong and continuous power support.
3. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
4. Adopt special magnetic ring inductor for audio to ensure the sound is clear and powerful.
5. PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents.
