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.
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
Frequency response: 20Hz to 20KHz
