Descriptions:
TPA3255 Four-channel digital Class D amplifier board
TPA3255 is a high-performance Class D power amplifier, which has Class D efficiency and can bring true high-end sound quality. There is an 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. Working 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 (such as 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). This can be achieved by 85mR MOSFET and optimized gate driver scheme.
 
Features:
1. Adopt original imported TPA3255 chip
2. The main filter electrolytic capacitor adopts a capacity of 470UF / 50V * 4, which ensures a strong source of continuous power support.
3. The resistor uses high-precision chip resistors to ensure a good signal-to-noise ratio.
4. Adopt special inductance for audio to ensure the sound is crisp and powerful.
5.PCB adopts 1.6mm thick double-sided board, 2.0 ounce copper thickness, and full tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality.

Basic performance parameters:
Working method: Class D
Quiescent current: 150mA
Work efficiency:.> 90%

Output Power:
315W / 4Ω, distortion 10% * 4
185W / 8Ω, distortion 10% * 4
260W / 4Ω, distortion 1% * 4
150W / 8Ω, distortion 1% * 4
